Animus Purge breaks Ruined Dungeon

[nehal]

So you can completely lock yourself out of the final room of Ruined Dungeon! Fun!

1. Use a Necromancer with at least one point in Animus Purge
2. Animus Purge to capture one of the Orb Guardians
3. Clear the Dungeon while keeping the Guardian alive
4. You are now left with one of the orbs inactive, and no way to activate it. Casting Animus Purge on the Guardian again results in it's disappearance, but the Orb doesn't trigger.
