Corrupted Map

Corrupted Map is an item used to locate a Cursed Crone arena near the player's current position. It is a progression-related utility item rather than a combat tool, and its purpose is to help players find the arena where the associated encounter can be fought.

Because it points to an arena around the player’s location, it is most useful when you are ready to begin or revisit that event and want to avoid searching blindly. Beyond that function, no additional behavior is provided by the available source material.
