Sudden Mindfulness

FEAT 1

Activity reaction

Trigger You roll a success on a saving throw against an effect that would make you Fascinated or Dazzled.

Your mind retains full awareness despite the best attempts of others, and your focus throws others off-balance. You get a critical success on the triggering saving throw, and if the triggering effect was caused by a creature, that creature is Off-Guard to you until the end of your next turn.
