Please, let's not spawn TWO concurrent monk threads. Suffice it to say that if we remove stunning from the stunning fist, then it's no longer stunning fist.

By making stunning fist function on things immune to stunning, such as:

Golems
Undead
Weapons
Brick Walls
Clouds
Jello
Doors
Potatoes
Candles
Books
Libraries
Armor
Water
Lasagna

We allow the monk, with a standard action, to full attack everything on a single attack. So, why not just call option 2(b) Pounce, plus an extra attack?

As for 1? DC 22 fort save vs Fort save bonus +19. Go ahead, make 4. Still won't help, and now that you've full attacked, let's let big monster eat you.
