Movie Summary
A Walks Through Walls bug. Very easy compared to older ways of doing it, like getting polymorphed by the mage champion during the boss fight.
Of course, you will have to be a mage to do it. If you're not a mage yourself, get a mage friend to do it, have yourself die from auto-unstuck, and have the mage mass rez you.
