Goblin Shaman is the most dangerous mob in the newbie area, and can manage to severely hurt an armored, fully trained character with the help of only one or two other goblins. He uses a number of spells, and ofttimes moves into melee range. Their melee attack has a small knockback effect and hits pretty hard at early stages of the game.
Goblin shamans almost always carry a staff of some sort. They also drop resin (usually 5) and bone (2+). Gold drops range from 10-15. They are a good source from which to get your first staff if not selected as a conscript weapon.
