Defeating Surtur in Infinity Gauntlet | Thanos Simulator on Roblox requires freezing him with the Snap of Ymir ability and damaging his torso with Disintegrate [E] ten times across two combat phases. Standard weapons cannot harm Surtur while he is active, and standing close triggers an immediate lethal stomp attack.
Requirements and Summoning Surtur
Before starting the battle, players must craft or acquire the Crown of Black Fire and possess the Heart of Ymir (obtained from World 5) to execute the Snap of Ymir.
To summon Surtur:
- Travel to the Catacombs and locate the main lava floor behind Jimmy Templar's shop.
- Locate the yellow pedestal featuring a yellow neon edge and Damascus steel texture.
- Interact with the pedestal to place the Crown of Black Fire.
- Immediately teleport or dash backward away from the altar. Surtur spawns directly on the pedestal and executes a stomp attack capable of instant elimination if you linger nearby.
Surtur Boss Stats and Phase Breakdown
According to the official community wiki documentation, Surtur has a total pool of 10 hit points, divided evenly across two distinct phases.
| Boss Phase | Health | Movement Speed | Active Moves and Mechanics |
|---|---|---|---|
| Phase 1 | 10 to 6 HP | Very slow (half player speed; accelerates ~20% per HP lost) | Fires 7 bouncing targeting magma projectiles; summons Servant Of Celestial [Dead] minions; stomps nearby players; freezes for 20 seconds via Snap of Ymir. |
| Phase 2 | 5 to 1 HP | Moderately fast (accelerates ~20% per HP lost) | Equips the Twilight Sword; casts unguided Magma Projectile Clusters (20 projectiles per burst); leaves lethal Lava Pools while walking; summons additional Dead Celestials. |
Boss Abilities and Hazards
- Stomp (Phase 1 & 2): Triggers whenever a player stands directly under or adjacent to Surtur. Has an area-of-effect radius of 40 studs and vertical reach equal to his leg height. Deals instant-kill damage.
- Targeting Magma Projectiles (Phase 1): Surtur hurls 7 fiery projectiles (0.5 seconds apart) at the player when 6 to 10 minions are present on the field. Each projectile deals 30 damage without register cooldowns, allowing multiple rapid hits to instantly kill. These projectiles ricochet off Catacombs walls.
- Servant Of Celestial [Dead] (Phase 1 & 2): Fast-moving minions boasting 45,000 health. They do not despawn, are immune to the freeze effect of Snap of Ymir, and can overwhelm or knock back the player.
- Lava Pools (Phase 2): Surtur drops lethal lava pools on the floor every 4 seconds while walking, or every 8 seconds while standing still. Touching these pools results in an instant kill. Pools despawn after 60 seconds.
- Magma Projectile Cluster (Phase 2): Erupts from the Twilight Sword in groups of 20 unguided projectiles every second. These behave erratically and spread outward in random trajectories, particularly while Surtur is frozen.
Step-by-Step Strategy to Beat Surtur
Because Surtur takes damage strictly through specific ability interactions, players must execute a precise freeze-and-strike rotation:
- Back Away Immediately: The instant the Crown of Black Fire is placed on the altar, retreat to long range to avoid the spawn stomp.
- Execute Snap of Ymir: Trigger your gauntlet's Snap of Ymir to freeze Surtur in place. This incapacitates him for up to 20 seconds.
- Fire Disintegrate [E]: Charge your gauntlet and fire Disintegrate [E] directly at Surtur's torso. A successful hit takes off 1 HP and causes a cluster of magma rocks to burst outward from his body.
- Evade While on Cooldown: Once struck, Surtur will unfreeze and retaliate. Keep your distance to avoid his stomp and ricocheting magma balls. Use high-mobility weapons such as Stormbreaker's Thunderslam [E] or teleport abilities to dodge incoming fire.
- Manage Phase 2 Movement: When Surtur reaches 5 HP, he equips the Twilight Sword and moves significantly faster. Watch the floor constantly to avoid stepping into the newly dropped Lava Pools, and maintain maximum distance while charging the gauntlet.
- Complete the Rotation 10 Times: Repeat the sequence of freezing with Snap of Ymir and firing Disintegrate until all 10 HP are depleted.
Bringing a partner who also possesses the Snap of Ymir simplifies the encounter, as players can alternate freeze cooldowns while keeping minions pushed back.
Patched Exploits and Safe Positioning Tactics
The community previously utilized instant-kill shortcuts, but developer updates have patched them:
- Time Stick Pruning: Teleporting to Surtur's shoulder to instantly prune his torso using the Time Stick has been confirmed patched.
- Decimate Exploit: Using the un-upgraded Infinity Gauntlet's Decimate [V] while Surtur was frozen is also confirmed patched.
- Catacombs Roof Positioning: Some players use Shiftlock or teleport tools to access the Catacombs' invisible barrier roof or Jimmy Templar's safe platform. From elevated barrier points, players can cast Snap of Ymir and aim downward with Disintegrate while avoiding melee stomp reach and ground lava pools.
Rewards for Beating Surtur
Defeating Surtur instantly rewards the player with his weapon and an official Roblox badge:
- Twilight Sword (Sword of Surtur): A lava-themed sword featuring a crescent hilt. Equipping it grants the user +10,000 max health (+20,000 total health if upgraded). Defeating enemies with the sword heals the player by 1 health point per damage tick taken by the target.
- Sword Abilities: The weapon features an M1 Slash (500 base damage plus 7,500 burn damage per second for 5 seconds) and an E Flamethrower attack that discharges high-velocity magma projectiles applying matching burn damage.
- Sword of Surtur Badge: Unlocks the official game badge featuring the description: "The crown is the source of his power, guess you just have to knock that thing off his head!"
Frequently Asked Questions
Can you damage Surtur with regular melee weapons or guns?
No. Standard attacks, normal gauntlet punches, and common weapons cannot lower Surtur's health. You must freeze him using the Snap of Ymir and hit his torso with Disintegrate [E].
What happens if you die during the Surtur boss fight?
Getting eliminated right upon placing the Crown may force you to restart the process all over again (including getting the Crown Of Black Fire). Always back away immediately when summoning.
Do Dead Celestial minions freeze when using Snap of Ymir?
No. Servant of Celestial [Dead] NPCs are immune to the freeze effect caused by the Snap of Ymir. Players must dodge or kite them while focusing Disintegrate on Surtur.
