Migo is a large Human male that has lost most of his mind due to Dallis, The Hammer's experiments.
If you can manage to kill him he will drop his armor. Note though that he is a very tough battle and shouldn't be taken lightly or fought early on, say pre-level 4 or so.
Extra Notes Edit
- Pick up a Yarrow Flower before talking to him, giving it to him will calm him down.
