Hello, I don't really follow speedrunning of this game but this happened to me during the hogsmead troll fight and thought it might be useful.

The troll charged me and looks like it went slightly outside of the fighting arena, up on the boxes, and instantly lost the rest of its health.

Might be worth looking into if there isn't already a better skip used.

I do believe this is a known hitbox bug and very rare that you get it. But we still appriciate the post always cool to see when this stuff happens. good luck on you're runs!
