Simply, the tree dungeon is a dungeon that generates on the surface as a bunch of trees. Currently there isn't much unique about this but I hope to add more things over time.

Nether Dungeons

Simply, it is a dungeon that generates in the nether with a pillar in the middle and lava at the bottom.

Pyramids

(yes yes a snow biome, they never showed up when I limited their spawning to sand.)
Simply, pyramids are pyramid shaped dungeons with a fountain in the middle and 4 random monster spawners. There is a chest hidden in the pyramid as well, try and find it.


The rarity is as rare as I can reasonably manage to get them. They have a 1 in 3 chance of checking a chunk, and a 1 in 100 (1 in 50 for nether dungeonsand 1 in 75 for pyramids but still very rare) chance of spawning there if the chunk is suitable. And a suitable chunk is rare.
