Mask of Fear

FEAT 13

Activity free action

Trigger You start your turn with the Frightened condition.

Requirements You're wearing your warmask.

Your warmask burns off of your face, releasing your apprehension. You remove the frightened condition. Your warmask is destroyed, and you can't reapply it until your next daily preparations.

Special You can use this free action even if you have a condition tied to the frightened condition that would normally prevent you from using a free action, such as "Fleeing as long as you're frightened" or "Paralyzed as long as you're frightened."
