Brutal Finish Feat 12
Source Pathfinder Core Rulebook
Requirements You are wielding a melee weapon in two hands
Your final blow can make an impact even if it rebounds off a foe's defenses.
Make a Strike with the required weapon. After the Strike, your turn ends. The Strike deals one extra weapon damage die, or two extra weapon damage dice if you're at least 18th level. The Strike also gains the following failure effect.
Failure You deal damage equal to one weapon damage die of the required weapon. Increase this to two dice if you're at least 18th level.
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.
FighterThis indicates abilities from the fighter class.
PressActions with this trait allow you to follow up earlier attacks. An action with the press trait can be used only if you are currently affected by a multiple attack penalty. You can't use a press action when it's not your turn, even if you use the Ready activity. Some actions with the press trait also grant an effect on a failure. The effects that are added on a failure don't apply on a critical failure. If your press action succeeds, you can choose to apply the failure effect instead. (For example, you may wish to do this when an attack deals no damage due to resistance.)
