Dead Cells

This is simply for arriving in the Bank level for the first time. The Bank entrance will randomly appear in a Passageway (area with vendors and potion refills between levels). It looks like a big chest that you can open and enter. It won’t appear in a save where you haven’t beaten Hand of the King once and it will never appear in a Passageway directly before a boss area as the Bank will replace the next area you would otherwise go to.

The Bank entrance will only appear once per run and will disappear if you don’t enter it. Unfortunately there’s no way to know which Passageway it’ll appear in during any given run, just that it will if you’ve previously beaten Hand.
