Tar Pool Dungeon

"I had been in one of the expansive caverns underground when I came across a pool of black, liquid tar, with some ruins around it. It was the perfect place to find submerged loot! Only, when I approached it, the tar suddenly rose into the air and molded into a red-eyed beast before my eyes."

-From Explorer's Entries: Pools of Tar

Tar Pool Dungeons are small, somewhat rare structures that generate in the Cavern and Lake Cavern layers. They are small, dome-shaped caves with a pool of Tar in their center. The pool contains Tar-solidified Pots with loot at its bottom, but also contains a Tar Beast spawner.

Due to the nature of Tar Beasts, this dungeon may prove very difficult to conquer. It is advised to empty the Tar pool before attempting to destroy the spawner and claim the items in the Pots.

Tar Pool Dungeons have a world location that identifies the area they take up, as well as a title that appears briefly to players who approach them.

Composition[]

Tar Pool Dungeons consist of:

Betweenstone
Tar, as a pool in the center
Betweenstone Tiles, rimming the pool
Betweenstone Brick Wall, sometimes in small poles surrounding the pool
Solid Tar, at the bottom of the pool
Tar Pot of Chance, at the bottom of the pool
Tar Beast Spawner, at the bottom of the pool

Mobs[]

The Monster Spawner in a Tar Pool Dungeon always spawns Tar Beasts.

Loot[]

Tar Pool Dungeon Pots use tar_pool_pot as their loot table.
