While exploring the archives for the 2nd seal to restore Zoltun I found a room that was stacked with strong enemies. I chose to retreat back through the doorway but found myself sealed off from the battle.
My templar and my spider could not cross the barrier, but if the enemies come close enough we can hit them for a few points of damage.
I suspect that I need to destroy the arcane construct to lower the field and so I fear that I'll have to backtrack a bit.
Is there any way to drop this door or is it a glitch?
