To get the Twilight Sword (also known as Surtur's Sword) in the Roblox game Infinity Gauntlet | Thanos Simulator by creator Blg42598, you must obtain the Crown of Black Fire through the Catacombs puzzle sequence and use it to summon and defeat the boss Surtur. Defeating Surtur drops the sword, unlocks the Sword of Surtur badge, and permanently grants your character a 10,000 health bonus.
Prerequisites and Required Gear
Before attempting the puzzle and boss fight in the Catacombs, ensure you have acquired the necessary tools documented in the official game records and community guides:
- Heart of Ymir / Snap of Ymir: Acquired from the sub-place known as The 5th World (or True World 5) after defeating Eson the Searcher. The Heart of Ymir enables the Snap of Ymir ability on your Infinity Gauntlet, which is mandatory to freeze lava, open puzzle doors, and stun Surtur.
- Infinity Gauntlet or Upgraded Infinity Gauntlet: You must have unlocked the Disintegrate ability (assigned to keybind E). Disintegrate is the primary attack used to break puzzle barriers, register code inputs, and damage Surtur's torso.
- Hadron Enforcer: A craftable heavy weapon needed to strip shields from celestial minions guarding the puzzle chambers and blast structural doors.
- Stormbreaker or Teleport Tools: Helpful for mobility and quick traversal through dangerous lava zones.
Step 1: Solving the Catacombs Puzzle for the Crown of Black Fire
The journey begins in the underworld lava region of the Catacombs. You must clear two gate chambers and complete a symbol code sequence before facing the boss.
- Open the First Chamber: Enter the Catacombs and activate the Snap of Ymir to freeze the ground environment. Charge your Hadron Enforcer or Gauntlet Disintegrate and shoot the target orb above the doorway. Step onto the platform inside once the lava returns.
- Open the Second Chamber: Perform another Snap of Ymir to cross safely. Target the second doorway orb with your projectile to reveal the inner altar.
- Insert the Heart of Ymir: Place the Heart of Ymir onto the pedestal inside the second room. This triggers a combat wave.
- Defeat the Celestial Servants: Multiple Servant of Celestials will spawn with active shields. Fire your Hadron Enforcer to shatter their shields, then freeze and eliminate them with Gauntlet abilities.
- Decipher the Code Room: Head into the lunar underbelly area behind the newly opened passage. A scanning entity checks the player, revealing numbered nodes. Zoom out your camera to observe glowing circular symbol patterns placed around the walls. Match each symbol to its corresponding digit (such as 3, 9, 7, 6, 11, and 5) and blast each numbered node in order using Disintegrate.
- Collect the Crown: Once all symbol numbers are correctly destroyed, the mechanism triggers and yields the Crown of Black Fire.
Step 2: Summoning and Defeating Surtur
Take the Crown of Black Fire back to the main lava floor of the Catacombs, located behind Jimmy Templar's Shop. Look for a Damascus steel pedestal with a yellow neon border.
Summoning Surtur
Interact with the pedestal to place the Crown of Black Fire. Back away or teleport immediately. As soon as Surtur spawns, he executes an instant-kill Stomp move with a 40-stud area of effect if the summoner is standing directly underneath or beside him.
Boss Phases and Stats
Surtur has 10 total health across two distinct phases. He does not take conventional weapon damage; instead, he takes exactly 1 damage per successful freeze-and-disintegrate cycle.
| Phase | Health Pool | Movement Speed | Attack Patterns | Damage Vulnerability |
|---|---|---|---|---|
| Phase 1 | 10 down to 6 HP | Very slow (half player speed, +20% per HP lost) | 7-projectile Magma bursts, Stomp (40-stud AoE), summons Dead Celestial Servants | Vulnerable only to Disintegrate [E] while frozen |
| Phase 2 | 5 down to 1 HP | Moderately fast (+20% speed per HP lost) | Spawns persistent Lava Pools, fires 20-projectile Twilight clusters, Stomp | Vulnerable only to Disintegrate [E] while frozen |
Combat Strategy
- Freeze with Snap of Ymir: Activate the Snap of Ymir to freeze Surtur in place. The freeze duration lasts 20 seconds.
- Strike the Torso: Charge your Infinity Gauntlet and hit Surtur's torso directly with Disintegrate (E). This reduces his health by 1 point.
- Clear Minions and Evade: When Surtur unfreezes from damage, he releases a burst of 10 to 11 magma projectiles. Back up, use your Shield ability (C), and avoid his Dead Celestial Servants (45,000 HP each).
- Repeat 10 Times: Execute the cycle of Snap of Ymir followed by Disintegrate a total of 10 times without dying.
Past community exploits using the Time Stick to prune Surtur or Decimate to one-shot him have been officially patched by the developer. The fight must be completed through the designated freeze-and-disintegrate rotation.
Twilight Sword Stats and Abilities
Once Surtur reaches zero health, the boss collapses and drops the Twilight Sword. Claiming it awards the Sword of Surtur badge.
- Base Health Bonus: Equipping or unlocking the sword grants +10,000 max health.
- Lifesteal Passive: Eliminating any NPC with the Twilight Sword restores 1 health per second for the amount of damage they take.
- Upgrade Path: The player can obtain the Upgraded Surtur's Sword, which awards an additional 10,000 health points (bringing the weapon bonus to 20,000 total health) and the Upgrade Sword of Surtur badge.

Frequently Asked Questions
Why does Surtur take no damage from regular attacks?
Surtur is completely immune to standard physical strikes, basic beams, and weapons like Stormbreaker. He can only be damaged by hitting his torso with the Gauntlet's Disintegrate ability while he is actively frozen under the Snap of Ymir.
What happens if I die during the Catacombs puzzle?
If you die to the lava or the Level 5 Celestial Servants before fully unlocking the Crown Room, the quest sequence breaks. You must reset the area and restart the room puzzles from the first chamber.
Can I defeat Surtur solo?
Yes. Soloing Surtur is fully possible if you own the Heart of Ymir and the Infinity Gauntlet. Having the Upgraded Infinity Gauntlet makes the fight significantly easier due to reduced cooldowns between snaps and defensive shields.
