Okay, so my Rogue Edwin was in a spot of trouble. I had given him the “What a Rush” Talent, which boosted his AP when at low health, though. He was very nearly dead, but I Fortified him to boost his armour, and Jahan then healed him, bringing his HP up to 30. It was 30, I checked. Then an undead archer attacked Edward and did 5 damage, (17 was absorbed), killing him. That’s bull. That’s wrong. He had 30 HP, he had no status effects. Taking 5 points of damage should not have killed him.

The only thing I can think of is that the undead archer landed a bleeding status effect, but that wasn't listed in the combat log, he just instantly dropped dead when his health should have been 25.
