Likely related to other recent changes; but bosses like Lich are super easy to trivialize by fighting them across the outside tip of a 90 degree corner.
Anwyays, in this positioning, they try to select their big magic aoes and cast them (animation goes off) but they don’t actually hit you even when you are melee’ing them. It’s blocked by the corner. I assume grim reaper has similar issue but haven’t tried it with him.
It’s very easy to replicate on Lich, especially HM Lich. Just wait at edge of corner outside his room. He’ll come out and come to you. Engage him right as he reaches the end of the hall and his side of that corner, but stay on your side of the corner. Melee him and then most of his big damaging abilities just don’t hit. Only his basic attack does. He’s still taking damage from your own attacks/spells and trivial to kill.
