Sry, had to do some celebrations.
As the King moves toward Marcello, he smirks in joy and swings his sword over his head.
AoO: 1d20 + 12 ⇒ (16) + 12 = 28
Damage AoO: 3d6 + 17 ⇒ (4, 3, 4) + 17 = 28
Taking the hit from the longsword makes a sickening crunch from Marcello as he curse his luck in chelixian.
After Sarcon moves into the position behind the King, Marcello only grins before letting another attack hit the undead opponnent. Serves him right for hitting him with his sword.
Attack: 1d20 + 15 ⇒ (17) + 15 = 32
Damage: 3d6 + 17 ⇒ (2, 5, 2) + 17 = 26
It is a +2 to hit from flanking, right?
WAIT! Doesn't my greatword do another die of damage because it is large?
