Arsenne announces: "I'm going to incapacitate it."

He then draws his right knee high up to his chest, and launches a flurry of short, shallow, non-lethal but powerful sidekicks downward at the prone Goblin-Monkey. As he strikes he shouts: "Dung Beetle SMASH"!

In order to make his kicks non-lethal, he strikes with the whole flat of the foot rather than focusing all his force into the heel.

If the Goblin Monkey is still conscious after that, Arsenne stands by with his right leg and knee chambered high in a pre-kicking position, ready to capitalize on any opening that the creature leaves him.
