Furious Finish Feat 2
Source Pathfinder Core Rulebook
Desperate to finish the fight, you pour all your rage into one final blow. Make a Strike. If it hits, you gain a circumstance bonus to damage equal to the number of rounds remaining in your Rage (maximum 10). After this Strike, your Rage immediately ends, and you are fatigued until you rest for at least 10 minutes.
