Trap: All monsters perform the Fight command.

Challenge: Heroes may not pass through doorways while moving.

Flavor Text: Why are doors always such a hazard to adventurers?! We came to a hallway where every door was guarded with some sort of dark magic, we could not open a single one! Somewhere behind us I heard the skittering of spiders and I knew we would either have to fight or go deeper into the tower...

We chose to keep moving.
