@KeijiSpoilercrit confirm - (1d20+1), (1d6+1). The shovel connects with the first orc's head from behind, crushing it like a melon.
The pick sinks into the side of the second orc, who attempts to break out of the melee. AoO - (1d20+1)(1d8+3). (You can take an AoO if you like) The last orc, seeing his companions dying, also attempts to flee.
