Bear obviously can instill fear through the village walls and through this KO someone. I stood inside a walled area, the bear started roaring, after a while running into the wall. I thought who cares.
Suddenly I was in attack mode and had "fear" 30% on me despite being several steps away from the wall. I was walking further away to stop adding fear but within a few steps I was knocked out with my black bile at 0. So it seems bear can through walls attack and their fear debuff decreases your black bile.
Is that intended or a bug? What about houses, they seem instanced, so at least inside a house or mine you are safe?
