Clocking a beast in the face sounds far more heroic.
Anyway I rolled for your sword, guess what? 20.
As his stance is open for attack, you charge at it again, With you're agility you manage to clock it in the stomach before it can claw you. After which you dash behind it, climb on it's back, and you behead it.
The beast has been slain, +80 exp to you good sir, for your valiance.
