Standard Dungeon Types

Cold Dungeon: The skeleton's bone cold abode

Mouldy Dungeon: This is your standard zombie spawner dungeon.

Webbed Dungeon: This dungeon could almost be mistaken for a small fortress... a spider's fortress.

[Found in: Plains, Hills, Savannahs, Tiagas, Forests]

Unique Dungeon Types

Ancient City Remnants: Warden worshippers having now long left the city leave it in disrepair. Find remnants across the deep dark and search it for unique ancient city themed loot!

Infested Dungeon: This mountain dungeon has been overtaken by an infestation! make sure you watch your step!

Insidious Dungeon: Well constructed dungeons using the locally abundant cinnabar and sulfur. Cave spiders lurk from within the dungeon turning whatever air space is left into a gorgeous network of webs.

Lush Dungeon: The lush jungles & caves provide a nice home for these cave spiders. Be careful however as the dungeon is very small & cramped.

Deepwater Dungeon: These are usually found below the depths of the ocean and in dripstone caves.

Frozen Dungeon: Wet and cold, this snowy dungeon brings with it a formidable stench from all of the strays.

Dusty Tomb: Mostly dry and sandy. The husk and parched are not very welcoming.

Scorched Tomb: Deep in the badlands these will be found. Dungeons full of zombies, skeletons and loot for those who do a little searching!

Muddy Dungeon: Can be found in the swampy areas of your world and is a haven to many bogged and slimes.

Other structures

Dungeon Ruins: We don't know how they got here, only that someone has been here already!
