Your bad luck seems reversed as you roll another 20.
As he scrambles to his feet, you push him down with your knee and slap on the cuffs. This makes things very difficult for him.
However, you had to touch him to get the cuffs on, and he's still on fire. You take six damage from the flames. He takes five, screaming in anguish as he cannot put it out himself.
The poison is also still in effect. Combat time ends with you on 58 damage, he on 60 damage.
In his current state, Tib is at a -2 penalty from his injuries and the cuffs. For a moment you don't think he's going to hit, but he spends a Fortune point and catches you in the stomach with his clawed heel. 9 damage to you...not good. At 60 you get a point of impairment, and at 65 you get another. All your rolls are at a -2 penalty...
Your responding punch is dodged; you JUST miss.
He takes advantage of your miss with a Headbutt...
