Heroes of the Monkey Tavern (EP)

The werewolf is one of the bosses of the game. You'll find him in the 7th level of the dungeon. All bosses (with the exception of the minotaur) can be killed in the same way, with weapons and spells of every kind. However, it seemed to me that the werewolf was particularly vulnerable to fire, so fireball-him to death, and the trophy should be yours.

Regarding the minotaur: you will encounter him in level 6. This is the only monster in the game that can't be killed with conventional means. There's a lever nearby that triggers poison darts. You have to lead the minotaur along that corridor and activate the lever. Only once he is poisoned will you be able to kill him.
