Current Behavior - Seems impossible for Neera or Dorn to be one-shotted (In Melee At Least). It seems the Max hit possible on them is Max HP minus 1. So if Dorn has 8 HP, the most he can be hit for at one time is 7. I've tested it with Dorn at level 1, and Neera at level 1 and level 2.
Expected Behavior - They should be able to be killed in one hit. No matter how hard I try I cannot get them killed in one hit. Even walking up to an ogre at level 1 completely naked, I cannot be one-shotted.
EDIT: This same issue may apply with spell damage also.. I will test it tonight.
