Finisher

Source Player Core 2 pg. 163
Finishers are spectacular finishing moves that use your panache. Finishers can be used only with weapons that deal additional damage with precise strike (agile or finesse melee weapons or unarmed attacks, for most swashbucklers). You can use a finisher only if you have panache, and you lose your panache immediately after performing a finisher. Once you use a finisher, you can't use actions that have the attack trait for the rest of your turn.

Some finisher actions also grant an effect on a failure. Effects added on a failure don't apply on a critical failure. If your finisher action succeeds, you can still choose to apply the failure effect instead. For example, you might do this when an attack deals no damage due to resistance.
