So from the description I think it's dead?
Torokk will close to adjacency and check it out. If it's still twitching he'll make an attack with his spiked gauntlet. In such a case, I assume it's Prone, granting +4 to attack rolls.
Move: move
Standard: attack with gauntlet
Attack (1d20+10)[12], I messed up the damage roll so made it in the OOC thread, for 10 piercing damage
