You've learned how to land daring blows when you have panache. You gain the precise strike class feature but you deal 1 additional precision damage on a hit and 1d6 precision damage on a finisher. This damage doesn't increase as you gain levels. In addition, you gain the Basic Finisher action. Basic Finisher [one-action] (finisher, swashbuckler) You make a graceful, deadly attack. Attempt a Strike; if you hit and your weapon qualifies for precise strike, you deal the full 1d6 damage from precise strike.
