[Just used 1 stunning strike, so just 1 CON save was needed.]
Drebash leans forward and seems to lose his balance. He puts his head down at the last moment to try and slam it straight into Arutha's groin. He rolls off and, now facing away, jumps straight up. With a hard kick of both feet backward, he tries slamming into the human's gut and pushing himself away. Turning the fall into a roll, he somersaults multiple times before standing and leaning back to look at his opponent upside down.

[Move 25' up
Attack
If one hits, again using Stunning Strike: DC13 CON save or be stunned until the end of my next turn. (Just 1 save needed)
Move 30' back away. Drunken Technique gives Disengage with Flurry of Blows (FoB) and 10' extra movement
Which should put 30' between us.]
