The Beatrice bonus round rule is one of the many rules that can be applied during the Bonus Round episodes. It is offered when either entering floor 4 or 5 as any character, but is rarer on floor 4.

Beatrice

On your first turn, all of your equipment is Shocked.

When this rule activates, you will always get Shocked 6 times on your first turn, blocking you from all of your equipment unless you use dice to remove shock (or sacrifice 3 health per equipment if the Warlock bonus round rule is active).
