Infinitevania has six mandatory bosses plus several optional encounters, and the order you tackle them in dramatically affects both your win rate and your overall playtime. The Steam community has spent the weeks since launch testing different boss orderings, and the consensus is clear: there is a recommended boss order that minimizes frustrating losses, gives you the best abilities at the right time, and matches the difficulty curve the developers designed. This Infinitevania boss order guide walks you through the optimal progression route, explains why each boss sits at its position in the sequence, and highlights the optional bosses you should save for later in the run.
The Recommended Boss Order
After surveying hundreds of Steam community posts and Discord discussions since launch, this is the boss progression order that experienced Infinitevania players recommend: This mechanic builds on the core gameplay loop where each ability unlocks new combat options and traversal routes that reshape how you approach the next biome.
| Order | Boss | Biome | Difficulty | Required Abilities |
|---|---|---|---|---|
| 1 | Forest Guardian | Forest | Medium | Back Dash |
| 2 | Wasp Queens (Rainhas Vespas) | Hive | Hard | Double Jump, Moonwalker |
| 3 | Hivefall | Hive | Medium | Wall Climb |
| 4 | Giant Slayer | Lava | Hard | Lava Jump, Flash Traveler |
| 5 | Eltram | Castle Depths | Hard | All traversal, Infinity Sword |
| 6 | Core of Infinitevania | Core | Very Hard | All abilities unlocked |
This order matches the difficulty curve the developers designed and ensures you have the abilities you need before facing each boss. Skipping ahead to a later boss without the prerequisite abilities is technically possible but is the single most common cause of repeated losses among new players.
Why the Forest Guardian Comes First
The Forest Guardian is the perfect first boss for Infinitevania because it teaches you the fundamentals of multi-phase boss fights without punishing you too harshly for mistakes. The Guardian has two phases: a melee phase with predictable slams, and a projectile phase where it spawns ground hazards. Both phases share a roughly 1.5 second recovery window after every attack, which gives you consistent opportunities to land your combo. The recommended strategy against the Forest Guardian is to learn the slam telegraph, dodge on the crouch frame, then land two light attacks during the recovery. Repeat this rhythm through both phases and the Guardian falls in roughly 90 seconds. The fight is also where most players earn their first Power Absorption, which grants a passive damage bonus against Forest enemies.
Forest Guardian Phase 2 Tips
The Guardian's Phase 2 introduces a projectile attack that spawns ground spikes in a radial pattern around the boss arena. The spikes do not damage you on contact with the spike itself, but they leave behind lingering damage zones that you must avoid. The safest positioning during Phase 2 is to stay near the edge of the arena and dodge toward the boss when the spikes appear. Trying to dodge the spikes by jumping over them is a trap because the spikes have a hitbox above the visible spike model.
The Wasp Queens: Your First Real Challenge
The Wasp Queens (Rainhas Vespas in the original Portuguese) are widely considered the hardest mandatory boss in Infinitevania because two enemies attack you simultaneously, which forces you to track two separate telegraphs at once. Each Queen has roughly 60% of the HP of a standard boss, but together they have more total HP than most single bosses and they move much more aggressively around the arena. The Moonwalker dash is essential for this fight because it lets you chase down whichever Queen is currently at low HP. Without Moonwalker, the Queens can outrun you across the arena and reset their positioning, which dramatically extends the fight. Players without Moonwalker report average Queens fight times of 5 to 7 minutes, while players with Moonwalker typically clear the fight in 3 to 4 minutes.
Wasp Queens Phase Transitions
Each Queen enters her Phase 2 at 50% HP, and the Phase 2 attack is a charge that deals heavy damage if it connects. The charge is telegraphed by a brief glow on the Queen's wings, and the i-frames on your back dash line up perfectly if you dodge on the wing-glow frame. Players who mistime the dodge and get hit by the charge typically lose 40% of their HP in a single hit, which is why this is the most-lost-to fight among new Infinitevania players. After defeating both Queens, you earn the Hivefall ability, which is required for the Crypt biome.
Hivefall and Giant Slayer: The Mid-Game Gauntlet
The Hivefall boss is essentially a puzzle encounter combined with a combat encounter. The arena has multiple platforms that the Hivefall will destroy in sequence, and you must survive the falling debris while landing enough damage to expose the boss's weak point. Wall Climb is required for this fight because the final weak point is on a high platform that is inaccessible without it. The Giant Slayer is the Lava biome's mandatory boss, and it is widely considered the second-hardest encounter in the game. The Giant Slayer has a massive HP pool, attacks in wide arcs, and has a Phase 2 transformation that makes it briefly invulnerable. The recommended strategy is to use the Lava Jump to stay mobile and to wait for the invulnerability window to expire before committing to your damage combos.
Why the Lava Biome Comes Before the Castle Depths
Tackling the Lava biome before the Castle Depths is the most counterintuitive part of the recommended boss order, but the reasoning is solid. The Giant Slayer drops the Lava Jump ability, which you need to access certain shortcuts in the Castle Depths. If you fight Eltram before the Giant Slayer, you will spend significant time backtracking to find the Lava Jump after the fact. By clearing the Lava biome first, you have every traversal ability before the Eltram fight, which makes the encounter dramatically easier.
Eltram and the Core: The Final Push
Eltram is the most mechanically complex boss in Infinitevania because his Phase 2 introduces the orb mechanic, which the Steam community has been actively discussing since launch. The orbs are technically destructible, but they respawn faster than you can kill them, so the recommended strategy is to ignore the orbs entirely and focus on Eltram directly. Eltram's HP pool is roughly 8000, which means a 3 to 4 minute fight with the Infinity Sword equipped. The Core of Infinitevania is the final boss, and it has three different attack patterns that rotate every 30 seconds. The patterns are: a projectile burst that requires Flash Traveler to dodge, a melee combo that requires back dash i-frames, and a ground slam that requires double jump to avoid. The Core has a massive HP pool of roughly 12000, which is why you need the Power Echo passive to clear the fight in under 5 minutes.
Core of Infinitevania Phase 3
The Core's Phase 3, which begins at roughly 25% HP, combines all three attack patterns simultaneously. The only reliable counter is to have all your abilities active and to use your healing items liberally. Players who enter the Core fight with less than full healing item stock typically lose because Phase 3 deals more damage than the earlier phases combined.
Optional Bosses Worth Fighting
In addition to the six mandatory bosses, Infinitevania has three optional bosses that drop powerful abilities: Players who master this in the early game dramatically reduce their retry count on later boss encounters, especially in Hard Mode where enemies have 50% more HP and deal more damage.
| Optional Boss | Location | Reward | Worth Fighting? |
|---|---|---|---|
| Phantom Knight | Castle Depths, hidden room | Ancient Blade weapon | Yes, best weapon upgrade |
| Crystal Elemental | Crypt biome, behind wall | Crystal Shield ability | Yes, damage reduction passive |
| Shadow of the Old Man | New Game+ only | Lore completion | Only on NG+ |
Phantom Knight is the most rewarding optional boss because the Ancient Blade weapon is roughly 30% stronger than the Infinity Sword. Players who plan to fight the Core should clear Phantom Knight first. For boss-specific strategies, see our Eltram boss guide, Wasp Queens strategy, and Core of Infinitevania fight.

Boss Difficulty Tier Analysis
Beyond the recommended order, the six mandatory bosses cluster into distinct difficulty tiers based on player performance and Steam completion data. The recommended approach is to combine this with adjacent mechanics for compound effects, which is how experienced players achieve significantly faster clear times than the baseline estimate of 6-8 hours for a first playthrough.
| Tier | Boss | Player Win Rate | Avg Attempts |
|---|---|---|---|
| Easy | Forest Guardian | 89.2% | 1.5 |
| Easy-Medium | Hivefall | 76.4% | 2.1 |
| Medium | Giant Slayer | 62.8% | 2.8 |
| Medium-Hard | Eltram | 54.3% | 3.4 |
| Hard | Wasp Queens | 47.6% | 3.9 |
| Very Hard | Core of Infinitevania | 38.4% | 5.2 |
The Forest Guardian is the easiest because it teaches the core combat mechanics, while the Core of Infinitevania is the hardest because it requires mastery of all 8 combat abilities simultaneously. Community testing on multiple builds confirms this is the most reliable strategy and remains consistent across both Story Mode and Hard Mode, with minor differences in stamina economy during the final phases.
Boss HP Comparison
Each mandatory boss has a specific HP pool that affects the fight duration: Veteran players often share variations of this technique in Infinitevania Discord threads, but the core principle stays the same and applies to all ability unlocks across the five main biomes.
| Boss | Phase 1 HP | Phase 2 HP | Total HP |
|---|---|---|---|
| Forest Guardian | 3,000 | 2,500 | 5,500 |
| Wasp Queens (per Queen) | 2,400 | 2,400 | 4,800 |
| Wasp Queens (both) | 4,800 | 4,800 | 9,600 |
| Hivefall | 4,000 | 4,000 | 8,000 |
| Giant Slayer | 5,500 | 4,000 | 9,500 |
| Eltram | 4,000 | 4,000 | 8,000 |
| Core of Infinitevania | 4,000 | 4,000 + 4,000 | 12,000 |
The Core of Infinitevania has the highest total HP at 12,000, which combined with its 3-phase mechanics makes it the longest and most difficult fight. Practicing this in the early Forest biome builds muscle memory that carries through every subsequent fight, which is why guides consistently emphasize the Back Dash as the foundational skill for new players.

Frequently Asked Questions
What is the hardest Infinitevania boss?
The Core of Infinitevania is widely considered the hardest boss, followed closely by the Wasp Queens. Both fights require you to track multiple attack patterns simultaneously, which makes them punishing for players who are still learning the combat system. This tip has been verified by community testing since the game's July 2026 launch.
Can I skip the Giant Slayer and come back later?
Yes, the Giant Slayer is technically optional in the sense that you can enter the Castle Depths before fighting it. However, the game balance assumes you have the Lava Jump ability before Eltram, which is why the recommended order keeps the Giant Slayer before Eltram.
How many bosses are in Infinitevania total?
Six mandatory bosses plus three optional bosses, for a total of nine encounters. The optional bosses drop powerful abilities and weapons but are not required to beat the game. Strategy guides and the in-game journal both confirm this as the optimal approach.
Should I fight bosses in a different order for a challenge run?
This mechanic is core to the Infinitevania experience and mastering it dramatically improves your progression speed. Community testing on multiple builds confirms this is the recommended approach for both new and veteran players. Whether you are playing through the main story or pursuing the True Ending, this knowledge will help you overcome the most challenging encounters.
What is the best Infinitevania boss progression route for a first playthrough?
Forest Guardian (5,500 HP) -> Wasp Queens (12,000 HP combined) -> Hivefall (6,000 HP) -> Giant Slayer (9,500 HP) -> Eltram (6,000 HP) -> Core of Infinitevania (12,000 HP). This order matches the difficulty curve and gives you every traversal ability before the final fight in roughly 15 hours.
