As long as someone can keep the healer's safe from AoO from the damned tiefling :0
Though if 17 hits the tiefling, Willow has hit him 3 times for quite a fair bit of damage ...
Yah, and what is the rule on ongoing poison when you go beneath zero ... does it continue, or does it stop then ??
If it stops once you are below zero, does Willow's regen also stop ??
Otherwise if the poison stops, but she continues to regen, she will eventually recover ... unless the encounter ends, in which case her regen stops as well ...
