Hollow Knight boss order: a practical progression path

Hollow Knight boss order: building a progression path through Hallownest

Working out a sensible hollow knight boss order is one of the first planning problems a new player faces, because the game never hands you a checklist. The world of Hallownest is open from very early on, and most bosses can be reached before you are ready for them. The map will let you walk straight from Greenpath into the City of Tears, or drop down into the Deepnest, even if the encounters waiting there were clearly designed for a stronger knight. The result is that progression feels less like a list and more like a branching tree, where a few boss fights are almost mandatory stepping stones and a great many others are optional side challenges that you can return to later.

This article treats the hollow knight boss order as a production design problem, not just a player’s checklist. Team Cherry built the world so that boss abilities gate the map, and boss rewards gate the rest of the bosses. Understanding that mechanism turns a confusing early game into a clear route. The structure below starts with how the game actually gates content, then walks through a recommended progression, separates the optional fights, and finishes with practical preparation for the hardest encounters. If you only need a quick list, the first table will give you a working order, and the rest of the article explains why each step works.

How Hollow Knight actually gates progression

Before listing a hollow knight boss order, it helps to understand the design pattern the game uses to direct players without a quest log. Three systems do most of the work: vertical map traversal, abilities that double as keys, and a difficulty curve that escalates as you move further from the starting area of the Forgotten Crossroads.

Vertical map traversal matters because the world is layered. The first time you drop into a new sub-area, the camera widens and you can see how much of the map you have not touched. The geometry itself suggests that you have arrived from a higher level, and that there is more below. That visual cue, combined with the soundtrack shifts and a denser set of enemies, is your real signal that a boss area is near. In production terms this is a passive navigation system: the level art communicates the next decision before any UI does.

Abilities that double as keys are the second gate. Each major ability, such as Mantis Claw, Monarch Wings, Isma’s Tear, Crystal Heart, and the Dream Nail, is also a traversal tool. Mantis Claw is required to reach some of the game’s harder early bosses because the walls leading to them cannot be climbed without it. Monarch Wings is required to cross certain chasms. Crystal Heart opens up new layers of the map. Isma’s Tear unlocks the ability to swim in acid, which in turn opens access to optional zones. The Dream Nail is technically optional for the main story but it is a hard requirement if you want to fight the more interesting dream bosses, including the dream variants of major characters. Because each ability is a key, the order in which you can find bosses is constrained by the order in which you can find abilities.

The third system is a soft difficulty curve tied to area. The first major boss is closer to the start, and the later optional bosses sit deep in the hardest biomes. This is not a strict lock, because you can reach almost any boss at any time once you have the movement set, but the encounter design assumes a player who has been through the earlier bosses. When you decide on a hollow knight boss order, you are really choosing how to use these three gates to your advantage: pick the fights that unlock abilities first, then use those abilities to reach harder fights when you are actually strong enough to win them.

Mandatory bosses versus optional fights

Not every boss is on the critical path. Some fights are required because they drop an ability, a charm, or a story item that the rest of the game depends on. Others are optional challenges that exist to reward exploration. Splitting the two groups makes the hollow knight boss order much easier to plan.

The table below groups the bosses by role. The “Critical” column lists fights that gate progress in some way, either because the game ends if you skip them, because you need their reward to reach the next area, or because the story is incomplete without them. The “Optional” column lists fights that are interesting but skippable. Most optional bosses still reward you with charms, geo, or lore, but the game can be completed without engaging with them.

Role	Bosses	Why it sits in this group
Critical progression	False Knight, Gruz Mother, Broken Vessel, Hornet (Greenpath), Hornet (City of Tears), Dung Defender, Crystal Guardian, Watcher Knights, Hollow Knight, Radiance	Each fight unlocks a key ability, blocks a key path, or is required to end the main story. Several are story beats that cannot be skipped without breaking the narrative.
Optional challenge	Vengefly King, Massive Moss Charger, Mantis Lords path boss, Soul Master, Oblobbles, Brothers Oro and Mato, Paintmaster Sheo, Great Nailsage Sly, Crystal Guardian 2, Uumuu, Marmu, Galien, Markoth, Elder Hu, Gorb, Xero, No Eyes, Traitor Lord, White Defender, Grey Prince Zote, Nightmare King Grimm, Hive Knight, The Collector, God Tamer	Reward charms, lore, and extra geo, but the main ending can be reached without fighting any of them. Some, like the Grimm Troupe content, are tied to optional content packs and event quests.
Difficulty tier hint	Each boss above sits in a tier from 1 (early game) to 5 (endgame)	Use this to decide whether a fight is appropriate for your current mask and soul meter.

You can read the table two ways. If you only want to reach the main ending, follow the critical row. If you want a fuller experience of Hallownest, weave optional fights in once your masks and charms are strong enough to make them reasonable.

Recommended hollow knight boss order for a first run

There is no single correct hollow knight boss order, because routes depend on which charms you have found and how comfortable you are with platforming. The path below is the one most players converge on without outside help, because it is the one the geometry of the map most strongly suggests. It assumes you are playing the base game, not a percentage completion run or a speedrun.

False Knight in the Forgotten Crossroads. The opening fight and the first real test of dodging and healing timing.
Gruz Mother in the same area. Forgives clumsy play and rewards you with a useful early charm.
Hornet in Greenpath. The first fight that demands real pattern recognition and unlocks the Dash Slash ability, which doubles as both a combat upgrade and a fast-traversal tool.
Broken Vessel in the Royal Waterways, reached through City of Tears after collecting Mantis Claw from Mantis Village. The reward is the Monarch Wings, which is the second key traversal ability.
Dung Defender in the Royal Waterways, optional from a story perspective but very useful for an early charm.
Soul Master in the City of Tears, optional but a strong source of soul regeneration charms and a good test of your aerial movement.
Crystal Guardian in the Crystal Peak area, the gate to Crystal Heart and the upper part of the map.
Watcher Knights in the City of Tears sewers, the gate to the Deepnest and to the Dreamers that block the Black Egg Temple.
The three Dreamers (Herrah, Lurien, Monomon) reached through Deepnest, the City, and the Fog Canyon. Defeating them is the critical path to the final boss.
Hollow Knight inside the Black Egg Temple, the main ending boss.
Radiance, the secret “true” final boss, unlocked by completing the Dreamers and a sequence of dream content. The hardest fight in the base game and the only boss that the developers balanced around an entire charm set.

This sequence is a working default. A player who is good at platforming can absolutely take the Mantis Lords earlier, because the Mantis Claw reward is one of the strongest abilities in the game. A player who struggles with timing may want to fight a few more optional bosses in between to collect masks and charm slots before tackling Watcher Knights. The For additional context, point of a hollow knight boss order is not to force a single route. It is to use boss rewards as a metronome so you do not arrive at a hard fight before you have the abilities that make the fight possible.

Side paths: optional bosses worth the detour

Optional bosses are where most of the replay value lives, but they are also the easiest place to overextend. The trick is to treat each optional boss as a question: do you have the masks, the soul, and the charm synergies to make this fight reliable, and does the reward justify the time spent? Below are the optional fights that are most often considered worth a detour during a first run, grouped by where they appear in the route above.

After Hornet in Greenpath: Massive Moss Charger in the area near the Greenpath benches. Drops the Heavy Blow charm, which is one of the best damage charms for the entire mid game.
After Mantis Claw: The Mantis Lords in Mantis Village. Optional as a fight, but their reward, the Mantis Claw, is mandatory for the critical path. Skipping them as a first encounter is possible, but the charm they drop is excellent for the Broken Vessel fight.
After Monarch Wings: Soul Master in the City of Tears. Drops a charm that increases soul regeneration, which makes every later fight easier.
After Crystal Heart: Crystal Guardian 2 in the upper Crystal Peak. A harder version of an earlier boss and a clean source of pale ore.
After Watcher Knights: Traitor Lord in the Queen’s Gardens, the test fight that decides whether you can handle the harder dream content. Defeating it opens a charm that helps against fast, multi-hit enemies.
After the Dreamers: Nightmare King Grimm, if you have been collecting the Grimm Troupe items along the way. The hardest content pack boss in the base game and a major charm source.

Notice how each optional boss is positioned just after a major ability unlock. The map and the ability order make these detours cheap, because you are already in the right region. That is the design pattern: optional bosses live in the area you are about to leave, not deep in a region you have not unlocked yet.

Difficulty tiers and what each tier means

If you only look at the names, the hollow knight boss order looks flat. The reality is that the game has at least five clear difficulty tiers, and a sensible order moves you from tier to tier so each new fight teaches you a skill the next one will demand. The next table maps the tiers to representative bosses, the new skill each one teaches, and a recommended preparation level.

Tier	Example bosses	Skill the tier teaches	Recommended preparation
1 (opening)	False Knight, Gruz Mother, Vengefly King	Basic dodging, healing timing, learning how soul works	Default masks, default nail, no charms required
2 (early)	Hornet (Greenpath), Massive Moss Charger, Mantis Lords path boss	Pattern reading, range control, jump-pogo tactics	At least one extra mask vessel, one charm notch, Quick Slash or Mark of Pride if found
3 (mid)	Broken Vessel, Soul Master, Dung Defender, Crystal Guardian	Multi-phase fights, projectile deflection, ground control	Monarch Wings, several charm notches filled, healing charms such as Quick Focus
4 (late)	Watcher Knights, Uumuu, Traitor Lord, Collector	Wave survival, heal prioritization, charm synergy planning	Most abilities, full mask set, soul and healing charms both equipped
5 (endgame)	Hollow Knight, Nightmare King Grimm, Radiance, Absolute Radiance in the post-game content pack	Frame-perfect evasion, equipment swap during combat, sustained pressure without heals	Full mask upgrades, full soul vessels, multiple specialized charm loadouts, Fragile Heart upgraded

The point of these tiers is not to gate content, but to make your decisions clearer. If you are stuck on a tier 3 boss and you have not unlocked Monarch Wings, the answer is almost always to go back and pick up the missing ability first, not to grind geo for more masks. A hollow knight boss order is, in practice, a sequence of ability unlocks disguised as a sequence of boss fights.

How to prepare for a hard boss

Because each tier has its own patterns, generic “git gud” advice tends to fail. The reliable way to prepare is to set up a small pre-fight routine and to keep it short. The steps below are the routine that experienced players use for the tier 4 and tier 5 fights, and the same routine works for tier 2 and 3 fights when you want a clean first try.

Reset your mask and soul state before the arena. Sit on the bench just outside the boss room, save and reload if you have to, and confirm that your current health and soul match the loadout you actually want to test. This sounds obvious, but most failed first attempts start with the wrong loadout because the player was experimenting earlier and forgot to switch back.
Pick a charm loadout, not a collection of charms. Two or three charms, with a clear role split between damage, healing, and utility. The classic late-game loadout is Quick Slash, Mark of Pride, and Quick Focus, but you can substitute Strength, Shaman Stone, or Spell Twister depending on whether you want a spell build or a nail build.
Identify the heal window before you start. Watch a short recording or your own previous attempt and find the two or three moments when the boss is fully off-screen or in a long recovery. Those are your only heal windows. Plan your entire fight around them.
Plan the first fifteen seconds. The opening of a boss fight is the part you are most likely to lose cleanly, because the patterns are unfamiliar. Decide in advance which direction you will move, whether you will use descending dark or great slash, and how you will break out of the spawn area if the boss is aggressive.
Stop after two failed attempts and reassess. If you have died in the same way twice, the next attempt will not be different. Change one variable, either a charm or the opening approach, instead of trying the same plan harder.

This is also a useful sequence to remember when you design your own content. Hollow Knight’s combat is built around windows, not around stats, and a good level teaches the player to read a window and use it. When you build a boss encounter, the equivalent design check is whether the player has a clear, repeated window that they can plan around, and whether the window appears often enough to keep the fight sustainable.

Boss abilities that double as map keys

One reason a hollow knight boss order feels so variable is that the game does not separate “movement progression” from “combat progression.” Several abilities are both. The next list calls out the boss rewards that you should treat as map keys, because they unlock new regions, new routes, or new shortcuts.

Dash Slash from Hornet in Greenpath. Doubles as a fast horizontal attack and a way to cross small gaps in mid-air.
Mantis Claw from the Mantis Lords path in Mantis Village. Lets you climb vertical walls, which is the first real “I can go anywhere now” moment.
Monarch Wings from Broken Vessel. Lets you double jump and reach areas that were previously one-way drops.
Crystal Heart from Crystal Guardian 2. A horizontal dash that doubles as a damage source and as a long-distance traversal tool across upper Crystal Peak.
Isma’s Tear from the optional Acid area, technically not a boss reward but obtained in an area gated by an optional fight. Lets you swim in acid pools, which opens the lower Royal Waterways and a small set of optional zones.
Dream Nail from a Seer in the Resting Grounds. The hard gate to dream bosses, including the dream variants of major characters and to the Radiance.

If you are following a hollow knight boss order and you realize you are missing one of these, the next step is almost always to detour toward it. Most players find that the detour is faster than trying to push forward with the wrong ability set, because the missing ability often solves a route problem that the player had been working around with awkward platforming.

How the optional content packs change the order

Several optional content packs add bosses and one full event quest, and they can be slotted into a hollow knight boss order in different places depending on how much of a detour you want. The list below covers the major content packs, the bosses they add, and where they fit best in the route described earlier.

Hidden Dreams. Adds a small set of dream bosses, including Xero, Gorb, and Elder Hu. Best slotted after the Dream Nail, which itself can be obtained any time after Resting Grounds becomes accessible, but practically after Watcher Knights because that is when you start dream content in earnest.
The Grimm Troupe. A full quest line with a normal boss, Troupe Master Grimm, and a harder version, Nightmare King Grimm. Best slotted after the Dreamers, because Grimm is at the same difficulty tier as Radiance. The reward charms are powerful enough to justify saving them for the final fight.
Lifeblood. Adds the Lifeblood charm and a small arena, not a full boss. The charm is a clean fit for any of the tier 4 fights, and many players use it as their safety net before attempting the Watcher Knights for the first time.
Godmaster. The post-game boss rush content. Adds several boss variants, including the Absolute Radiance, the Pantheons, and a tougher version of the final boss. Best slotted after the main ending because the difficulty is calibrated for full mask and full charm loadouts.

These packs do not change the critical path. They are bolted onto the same world and they use the same abilities, so the gate logic still works. The only adjustment is that some charms from these packs are so strong that they will change how you approach the main route if you use them too early. As a general rule, save the post-game content for last, slot Grimm in just before Radiance, and treat the Hidden Dreams bosses as a way to practice dream combat patterns in a lower-stakes setting.

Common progression traps and how to avoid them

Most players who feel that the game is unfair are not actually stuck because the fight is too hard. They are stuck because they are missing an ability, a charm, or a heal window. The list below is a quick reference of the most common progression traps, in the order you are most likely to hit them while following a recommended hollow knight boss order.

Going to Deepnest too early. The Deepnest has an open entrance, but the geometry, the enemy density, and the boss fights are calibrated for late-mid game. If you arrive before Monarch Wings and before you have any healing charms, you will be chased out repeatedly. The fix is to leave and come back after the City of Tears content.
Skipping the Mantis Lords path. The Mantis Village is easy to walk past, because there is no marker telling you that the path leads to a critical ability. The trap is to assume the path is optional. It is not, in any practical sense, because the Mantis Claw is required to climb the walls leading to several later bosses.
Fighting Watcher Knights without a heal charm. Watcher Knights is the first fight that has very few safe heal windows. Players who arrive with only the default healing pattern usually fail the second phase. The fix is to slot Quick Focus or Shape of Unn and to learn the one moment between waves when you can heal.
Missing the Dream Nail. The Dream Nail is an item you pick up from a Seer in the Resting Grounds. It is not given to you by a boss, which is why some players miss it entirely. The trap is that without the Dream Nail you cannot fight the Dreamers in their dream states, and the story soft-locks. The fix is to backtrack to Resting Grounds as soon as you have enough soul capacity to find the Seer.
Forgetting to upgrade the nail. The Pale Ore you find scattered through the world upgrades the nail’s damage, which is the single biggest stat boost in the game. The trap is that ore is rare and easy to spend on a charm by accident. Save it for the nail.

How this progression map applies to the developer’s perspective

It is worth stepping back from the player’s checklist, because a hollow knight boss order is also a case study in open-world game design. Several of the techniques Team Cherry used map directly to common game development problems.

First, the world is gated by ability rather than by level number. There is no “you must be level 7 to enter Deepnest” check. Instead, the walls and ceilings require Mantis Claw, Monarch Wings, and Crystal Heart. The player is the one who decides when they are ready, because the geometry tells them when an area is reachable. The equivalent in your own project is to design doors that the player can see but not open, then teach the player the key by giving them a fight.

Second, the difficulty curve is layered, not linear. A player can be defeated by the Watcher Knights on a first attempt, but they will rarely be defeated by the same fight on a second or third attempt if they have spent the time in between exploring the area and learning the heal windows. This means the game trusts the player to use failure as a learning tool. The design lesson is that boss encounters should be repeatable without punishing the player for the attempt, and that the penalty for death should reset the world state but not the player’s knowledge.

Third, the optional content is geographically woven into the critical path. The Mantis Lords are in a village that you walk past to reach the City of Tears. The Crystal Guardian 2 is in an upper area you would have to backtrack through anyway. The Grimm Troupe campfire is just off a bench you already use. This means that the optional content is a tiny detour rather than a separate game, which keeps engagement high without adding a second progression bar.

Finally, the boss abilities are designed to be load-bearing tools. Dash Slash is also a combat move. Mantis Claw is also a map key. Crystal Heart is also a dash attack. Every reward is a small rework of the player’s kit, which keeps the late game feeling fresh without an actual level-up screen. The lesson for designers is that progression systems should change the verbs of the game, not just the numbers. A “+5% damage” buff is forgettable, but a new movement option is a new way to think about every encounter.

A short checklist before any boss fight

Below is a condensed checklist that captures the practical advice above. Use it before each boss fight, not just the hard ones, because a clear pre-fight routine tends to be the difference between a clean attempt and a grinding death loop.

Confirm the loadout you want to test.
Confirm your mask and soul state.
Identify at least one heal window.
Plan the first fifteen seconds.
Decide which charm you will swap if your opening does not work.

That is the entire routine. If you can answer each line confidently, you are ready for the fight. If you cannot, you have a specific thing to learn before your next attempt, which is the only kind of progress that actually carries forward.

Where to go from here

If you have worked through the recommended hollow knight boss order and the optional detours that fit your route, the next sensible step is to look at the broader progression of the game rather than the next single boss. The same gating logic, the same difficulty tiers, and the same ability-as-key pattern apply to the post-game content, and understanding the pattern is what makes the harder fights feel learnable rather than random.

For readers who are interested in the structural side of the design, the Wikipedia article on Hollow Knight gives a concise summary of the game’s release history, its place in the wider Metroidvania genre, and the design context that shaped the progression. For readers who are interested in how the game has been received and how its content packs were released over time, the Eurogamer piece on hollow knight’s physical release is back on, includes fancy collector’s edition gives a clear view of the broader rollout and the relationship between the digital version and the collector’s edition.

The remaining section answers the most common follow-up questions that come up while planning a hollow knight boss order, with practical detail rather than just a name and a one-line description.

Frequently asked questions

What is the shortest hollow knight boss order to reach the main ending?

The shortest realistic route is False Knight, then Gruz Mother, then Hornet in Greenpath, then the Mantis Lords path to pick up Mantis Claw, then Broken Vessel, then the three Dreamers, then the final boss inside the Black Egg Temple. Most players can clear this set in roughly 25 to 35 hours, depending on how much optional exploration they pick up along the way. Skipping optional bosses is the main way to shorten the run.

Can I fight Hornet in the City of Tears before the Mantis Lords?

You can reach her arena, but the fight is much harder without Mantis Claw, because you have less control over vertical movement during her multi-hit combos. The intended order is Hornet in Greenpath first, then the Mantis Lords path, then Hornet in the City of Tears. If you want to fight her early as a personal challenge, expect to spend more attempts and to take more damage than the developers balanced for.

Do I need the Dream Nail to finish the main story?

Yes, in practice. The Dream Nail is required to put the three Dreamers to sleep, and that is the gate to the final boss. If you want the “true” ending and the Radiance, you also need the Dream Nail upgrades, which means more dream content. If you are happy with the standard ending, you still need the base Dream Nail to put the Dreamers to sleep.

Where do the Mantis Lords fit into the hollow knight boss order?

The Mantis Lords are technically optional, but the Mantis Claw they gate is not. Most routes treat the Mantis Lords as a critical fight, because the wall climb they enable is required to reach Broken Vessel, Watcher Knights, and most of the late game. The Lords are also a good source of the Mark of Pride charm, which is one of the best mid-game damage charms.

What is the best charm loadout for a first playthrough?

For the early game, Quick Slash and Mark of Pride give the biggest damage increase. For the mid game, add Quick Focus to keep your heal timing safe. For the late game, the classic build is Quick Slash, Mark of Pride, and Quick Focus, with Shape of Unn or Grubsong as a defensive choice when you are learning a new boss. There is no single correct answer, because charm slots are limited, but the Quick Slash, Mark of Pride, Quick Focus set is a reliable default.

Are the dream bosses required for the main ending?

No. The three Dreamers are required, but the dream variants of other bosses, such as the dream warriors in the Hidden Dreams content pack, are optional. They reward extra charms and lore, but the game can be completed without them. If you want the Radiance, you need to complete enough dream content to access the dream sequence that opens the final fight.

How do I prepare for the Watcher Knights specifically?

Watcher Knights is the first fight with very few heal windows, so the preparation is more about pattern reading than about raw stats. Make sure you have at least one full extra mask, a healing charm, and a way to clear the rolling ball attack that appears between waves. Practice the first two waves until the heal windows are obvious, then push for the third and fourth waves. Most first-time clears happen in the second or third attempt after a clean pre-fight routine.

Is the Grimm Troupe content worth doing in a first playthrough?

Yes, if you want the hardest boss in the base game and a set of very strong charms. The Troupe adds a full quest line, two bosses, and several charm upgrades. The main cost is the time it takes to find the troupe’s tents, which is one of the longest side quests. If you are doing a completion run, slot the troupe in just before the final fight, so the charms you earn are available for the endgame.

How long does the game take to beat if I follow a hollow knight boss order?

A focused first run that follows a recommended hollow knight boss order and includes the main critical path takes roughly 30 to 40 hours. A run that includes most of the optional bosses and content packs takes roughly 50 to 70 hours. A full completion run that includes every charm, every mask, and the post-game boss rush takes longer, because the boss rush alone is several additional hours of repeated attempts.

What is the best way to plan a hollow knight boss order for a challenge run?

For a challenge run, the planning is the run. Pick a constraint, such as no charms, no healing, or a specific boss first, and then design a hollow knight boss order that makes the constraint hardest at the most interesting moment. The order above still works as a skeleton, but the optional fights become the place where the constraint is most exposed, so slot them in early rather than late to find out whether the constraint is survivable.
