Infinity Gauntlet Thanos Simulator Heart of Ymir Unlock Guide

The Heart of Ymir in Blg42598's Roblox title Infinity Gauntlet | Thanos Simulator is an endgame relic obtained by conquering The 5th World and defeating Eson the Searcher. Acquiring this relic grants permanent freeze chances, bonus health, and unlocks the Snap of Ymir, while also serving as a mandatory prerequisite for progressing toward Surtur's Sword.

Heart of Ymir Overview and Weapon Stat Buffs

Acquiring the Heart of Ymir awards the in-game badge "World5." and applies substantial passive buffs to the Infinity Gauntlet, the Upgraded Infinity Gauntlet, and the Casket of Ancient Winters.

In PvP mode, the Infinity Gauntlet's base M1 shifts between 21 and 22 damage with a 50% freeze chance, while Focus M1 scales to 107 damage. The Upgraded Infinity Gauntlet PvP M1 scales to 99 damage (495 in Focus) with the 50% freeze chance applied.

Required Weapons and Prerequisites

Attempting the 5th World sub-place unprepared will cause quick failure. The community meta and game mechanics require specific gear:

1. Hadron Enforcer: Crafted using celestial scrap and fragments. Pre-charging its projectile (M1) is mandatory to damage the boss's eyes and exposed brain.
2. Infinity Gauntlet or Upgraded Infinity Gauntlet: Needed for its Shield (C key) to block laser projectiles and Focus (R key) for emergency healing.
3. Stormbreaker or Upgraded Stormbreaker: Needed for the Thunderslam (E key) to jump up through the exit shaft once the boss is defeated.
4. Optional Support Weapons: The Scepter game pass provides 2x walkspeed and heals 1/20 of maximum health per second. The Tesseract weapon can also be used to teleport across moving platforms and restore 21.55% maximum health per cast.

Step 1: Collecting Frost Fragments and Teleporting

Before you can access The 5th World (also known as True World 5, not to be confused with standard World5 where Lazarus resides), you must activate the central portal beneath the spawn island:

1. Farm NPCs wearing gift hats (Present3 NPCs, which have a 3/24 spawn rate on the main map).
2. Collect 8 Frost Fragments. The player inventory caps at 8 fragments.
3. Travel directly below the central floating spawn island to find the circular portal surrounded by 8 outer rings.
4. Click the floating blue orb in the middle. The 8 outer circles will light up, consuming your fragments and teleporting you to The 5th World.

If you fail or die during the boss challenge, you will lose fragments (community gameplay notes you lose at least one fragment upon death, while wiki notes describe losing a random quantity) and must re-farm them before re-entering.

Step 2: Clearing the Mountain Entrance

Upon loading into The 5th World snowy landscape, standard teleport abilities and the Infinity Gauntlet's Focus ability remain disabled until the boss arena:

1. Approach the entrance at the foot of the mountain guarded by 5 Erde NPCs.
2. Maintain maximum distance. These guards deal lethal damage if you enter melee range.
3. Eliminate all 5 guards using ranged attacks, such as Upgraded Stormbreaker's lightning strikes or gauntlet ranged abilities.
4. Walk through the entryway to enter Eson the Searcher's chamber.

Step 3: Defeating Eson the Searcher

The boss fight begins when you step onto the platform. The floor acts as a moving conveyor belt that drags your avatar toward lethal hazard barriers:

1. Manage Movement: Never stop walking forward. Touching the yellow hazard barrier on either side causes instant death. As you break eyes, the floor moves progressively faster and may shift directions. Use weapon dashes (such as The Secret Weapon or Thanos Blade Dash) to maintain positioning against high conveyor speeds.
2. Dodge Floor Hazards: Ground markers will appear that shoot vertical beams upward. Dodge them actively or keep the Gauntlet Shield active.
3. Shoot the Eyes: Listen for a horn-like sound that blasts three times. One of Eson's six eyes will begin flashing. Immediately fire your pre-charged Hadron Enforcer projectile into the flashing eye to dislodge it.
4. Tank the Floating Eyes: Dislodged eyes float nearby and constantly channel damaging lasers at you. They cannot be damaged or killed. Keep your Gauntlet Shield raised to block the barrage. When health drops, trigger Focus (R key) to regenerate health, or rely on Scepter/Tesseract passives if owned.
5. Repeat for All 6 Eyes: Cycle between shielding, moving against the conveyor belt, pre-charging the Hadron Enforcer, and shooting each flashing eye until all 6 have been dislodged.
6. Destroy the Exposed Brain: After all 6 eyes are removed, the head explodes to reveal Eson's brain. Fire one final charged Hadron Enforcer projectile directly into the brain to end the encounter.

Step 4: Claiming the Relic

Once Eson is destroyed:

1. Proceed through the corridor opened behind where the head was located.
2. Locate the overhead opening in the ceiling.
3. Equip Stormbreaker and use Thunderslam (E key) to boost upward through the shaft.
4. Walk to the end of the elevated hallway and interact with the floating orb on the pedestal.
5. The game will grant the "World5." badge, adding the Heart of Ymir and its passive benefits permanently to your account profile.

Using Heart of Ymir to Progress to Surtur's Sword

In addition to combat stat boosts, the Heart of Ymir is a mandatory quest item required in the Catacombs:

• Unlocking True Catacombs: Equip the completed Infinity Gauntlet and execute the Snap of Ymir (Q while charged) to freeze the Catacombs lava.
• Opening the Pedestal Chamber: Use Disintegrate (E key) on the sealed doors. Inside the right-hand door, place the Heart of Ymir upon the pedestal to spawn Level 5 Servants of Celestials and begin the puzzle chain for the Crown of Black Fire and Surtur's Sword.

Frequently Asked Questions

Can the floating eyes in the Eson boss fight be killed?

No. The official wiki confirms that the dislodged floating eyes cannot be damaged or destroyed. Players must survive their laser attacks using the Gauntlet Shield or health regeneration tools until the fight ends.

Do you lose all Frost Fragments if you die in The 5th World?

If you die during the encounter, you will lose fragments. Player testing records losing 1 fragment per failed attempt, while wiki entries state a random amount is lost. Keep spares or farm Present NPCs again to reach the 8-fragment threshold.

How does Snap of Ymir work once unlocked?

Snap of Ymir requires all six Infinity Stones and the Heart of Ymir. Charging the Gauntlet with Q reveals the Snap UI. Activating it creates an infinite-range freezing field that freezes standard NPCs for 60 seconds and Surtur for 15 seconds, followed by a 13.5-second cooldown.
