Yo, just gather 10 Withered Bones, head to the swamp altar with the skull, and summon Bonemass. It's that simple.

Find Withered Bones in swamp crypts and offer 10 of them at the altar with the skull in the swamp. Happy hunting!

I just battled Bonemass last night! Scope out a swamp biome, find a skull altar, and sacrifice 10 Withered Bones. Don't forget poison resistance mead!
