'''Strategy (Epic):
He suffers from a very annoying bug that happens almost every single run where he gets stuck in a teleport loop and becomes extremely hard to damage. Luckily there is a workaround: Gather you entire party on the crate in the center, and cast mass invisibility. Baktor will become confused trying to find you, and reset his AI, fixing the bug. Regular invisibility cast on everyone one at a time can work also, just faster and easier with mass.

Alternatively if you have no access to invisibility you'll just have to beat him down with the bug, Blade barrier is rather effective when he's in this state.}}
