Sedusa Medusa
In the center of the room are two statues, a human looking over his shield and opposite him a medusa. Around his neck is an obvious key, it is the key to the next room.
Blocking line of sight of the soldier to the medusa revives him. He will offer the key in exchange for someone swapping places with him to hold the shield, if the shield moves too far, the medusa comes back to life.
