Thanks Masamune, confirmed and being worked on. We're checking Final Attack for every class that has it (the Warrior, Bowman and Cygnus versions alike), not just the Dawn Warrior buff, so they all trigger the way they should. Will update here when it's in the game.

Thanks Masamune, you were right, and it turned out to be bigger than the Dawn Warrior. Final Attack was only checking for a trigger on plain attacks, so Power Strike, Slash Blast and Brandish never set it off, even with the buff up. That was true for every class that has Final Attack. Now it triggers from the right skills everywhere: Power Strike and Slash Blast for Fighters, Pages and Spearmen; Power Strike, Slash Blast and Brandish for Dawn Warriors while the buff is up; the shot skills for Hunters, Crossbowmen and Wind Archers. Plain attacks no longer set it off. At your level 8 it has about a 1-in-6 chance after each of those skills and hits for 140%. After Slash Blast it hits everything Slash Blast hit. LIVE now (refresh the game to pick it up).
