To get the Universal Weapon in the Roblox game Infinity Gauntlet | Thanos Simulator (created by Blg42598), you must enter the Catacombs and defeat the rare boss variant named Servant of Celestial [Rare]. The boss has a base spawn chance of roughly 0.03% (1 in 3,333) whenever regular Celestial enemies spawn, and the player who deals the final killing blow is awarded the weapon alongside the official badge.
Prerequisites to Enter the Catacombs
Before you can hunt for the Universal Weapon, you must unlock access to the Catacombs.
- Required Badge: You must have earned the Stormbreaker badge, which requires forging the Stormbreaker weapon at the Forge for 100 fragments and 250 kills.
- Entrance Location: Head to the edge of the map on the opposite side of the main Forge. Interact with the blue stone structure to teleport down into the Catacombs.
- Inventory Check: Entering the Catacombs will automatically place the Infinity Gauntlet and Stormbreaker into your inventory if they are not already equipped.
Equipping your unlocked weapons before dropping into the combat zone is recommended because holding multiple weapons increases your overall maximum health pool.
Spawning the Rare Servant of Celestial
The Catacombs feature a volcanic cavern split into an upper level and a lower level. Level 1 Servants of Celestial spawn in the upper section, while Level 2 variants populate the lower area. The boss you need to find replaces these standard spawns.
- Spawn Rate: The Servant of Celestial [Rare] has an initial 0/3,333 (0.03%) spawn chance. Every time a Level 1 or Level 2 Celestial spawns, +3 is added to the numerator for that specific area until the rare variant appears. Once spawned, that section's counter resets back to 0.
- Appearance: Regular Level 1 and Level 2 servants are yellow-orange robots with three or four eyes. The rare variant is distinctly purple, features six glowing neon eyes, and wields the Cosmi-Rod warhammer.
- Despawn Rules: Rare Celestials do not despawn. There is no hard cap on how many rare variants can exist in the upper or lower sections at once, and they will remain in the cavern even if you die.
Grinding down groups of Level 1 and Level 2 enemies forces respawn waves. Standard mobs deal 1,250 to 2,500 damage per hit and can knock you into the lava, which inflicts 10,000 flat damage unless mitigated by a defensive shield.
Boss Fight Strategy and Mechanics
The Servant of Celestial [Rare] functions as a high-threat mini-boss with heavy melee output.
| Boss Attribute | Value |
|---|---|
| Total Health | 1,100,000 HP |
| Melee Hammer Smash Damage | 160,325 damage |
| Attack Rate | 1 hit per second |
| Kill Reward | 9 kills + Universal Weapon unlock |
| Health Regeneration | None |
Because the boss has 1.1 million HP and can defeat unprepared players in a few hits, keep the following combat mechanics in mind:
- Zero Regeneration: The rare boss has no health regeneration mechanics. If you die during the fight, respawn, re-enter the Catacombs, and resume attacking where you left off.
- Crowd Control: Players frequently use the Time Stone's time-freeze ability (activated with T) to immobilize the boss. Freezing the boss prevents its hammer smashes from connecting while you unleash damage.
- Shielding: Activating the Infinity Gauntlet's shield (C keybind) blocks incoming melee strikes and protects against environmental lava damage.
- High-Damage Weapons: Weapons such as Mjolnir or Stormbreaker deal substantial area damage and ground pounds, allowing you to chip away at the boss's large health pool safely from mid-range.
Make sure you deliver the final blow yourself if playing with others, as the game awards the weapon and badge strictly to the player who scores the fatal hit.
