Kurtz' Stache

It opens up after the player is inflicted with 10 curses after picking up this item, dropping 15 items which can be Basic Items, Potions, or Blessings. The Curses do not have to be different types.

Getting rid of Curses will not change your progression towards opening it.

The curse count will get reset if it is placed on the Relic Altar.

As of the Supply Crate Update This relic can only be found after 5 full runs of Undermine.
