The Engulfer

The Engulfer, a new monster haunting the deep caverns below the Purple Sword Crags - some say it is a twisted, mutated abomination that once was a treeman... Other say it is the creation of some mad wizard and driven by a powerful spell bound around the three owls in its forehead!
The only way to stop it is to take the owls out. And they call him the Engulfer as he has reportedly devoured more than one mighty hero trying his luck against the abomination.

The monster comes with two different sets of mushroom caps.
