Ward Mind

FEAT 16

Activity reaction

Requirements You're currently affected by a mental effect that you gained by failing, but not critically failing, a saving throw.

Trigger Your turn ends.

To protect the knowledge within your mind from intrusion or erasure, you ward yourself against a mental attack, temporarily delaying its effects. Until the end of your next turn, you ignore a single mental effect that meets the requirement. You can suppress a particular effect using Ward Mind or Cognitive Loophole only once, even if you have both feats.

Special You can use this reaction even if the mental effect prevents you from using reactions.
