bandit, usually guarding the bridge across the entry corridor. continue round past another chest towards the exit.
this zone takes the form of one large cave that curves around like a question mark from the perspective of somebody entering. there will be a maximum of only three bandits in this area, one of which is a boss. if possible try to kill the others off first.
one may be directly in front of you when you enter the cave; the next will be around to your right. a sneaky arrow shot should take care of them. after that you can head for the boss in relative safety.
