To unlock the Cape in Idle Slayer, you must complete a specific Master Quest and purchase a very expensive upgrade.
1. Complete the Master Quest: Chemical Components
The first crucial step in unlocking the Cape is to successfully finish the Master Quest titled Chemical Components. Master Quests are significant in-game challenges that often serve as milestones for progression, requiring players to meet certain criteria or overcome specific obstacles.
2. Purchase the Warming Up Upgrade
After completing the Chemical Components Master Quest, you will then need to acquire the Warming Up upgrade. This upgrade comes with a substantial cost of 1.00e37 coins. For easier understanding, this amount is also referred to as 10 Ud (Undecillion) coins, indicating that the Cape is an end-game or very late-game item requiring considerable wealth accumulation.
