You'll have your hands full if you dash into this room. Here's how the game works:
1)You can't hit the wolves in the cage until it opens.
2)The cage will open once you cross the threshold into the room.
3)The Pack Leaders inside won't leave their cage if you aren't in the room.
This room becomes embarassingly easy if you use ranged attacks from the hallway until all but the caged wolves are eliminated. Then step into and back out of the room during one movement phase of turn-based mode. The cage will open but the Pack Leaders won't advance.
