After my Kron the Undyng reached the first postion and got Last Stand he has speed 3 and Djinn Oshanus Speed 5 - Their is no other speed buff I can see so the chance to miss is 20%.
But he miss three times in a row and I loose the fight:

My chance was (20% x 20% x 20%) 0,8% or once in 125 battles and I took it.
