Boss Readiness Checklist
The Boss Readiness Checklist helps you confirm prerequisites before starting long boss attempts in Infinity Gauntlet Thanos Simulator. Select a target boss and check off required stones, weapons, and map progress. Data saves locally in your browser.
Supported Boss Targets
- Power Stone NPC — Shield + Focus rhythm at the Power Temple
- Doom — Update 3.2 summon with Mjolnir, Hadron Enforcer, and Classic Snap
- Eson the Searcher — World5 celestial requiring Hadron Enforcer eye shots
- Surtur — Full Catacombs chain with Heart of Ymir and Crown of Black Fire
- Lazarus — World5 expansion boss tier content
- Astra — Advanced World5 celestial encounter
How to Use
Choose your boss from the dropdown below. Mark each prep item as you complete it in-game. When every box is checked, you are ready to commit to the attempt. Pair this tool with the stone checklist and kill tracker for full progression planning.
Why Prep Matters
Endgame bosses like Surtur and Doom punish missing prerequisites with full resets. Power Stone NPC wastes time without Shield. Eson is impossible without Hadron Enforcer. Use the linked guides when a checklist item is unclear.
