Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
FinisherFinishers are spectacular finishing moves. 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. If your finisher succeeds, you can choose to apply the failure effect instead.
SwashbucklerThis indicates abilities from the Swashbuckler class.
