This mod significantly improves dungeons in Minecraft. It makes them much larger with many maze-like corridors and rooms. You’ll see them scattered throughout your travels but unlike normal dungeons, these will be found with entrances above ground.
You’ll drop into mostly darkness, so be prepared with many torches to light your way. Mob spawners and enemies will be plentiful so arm yourself well.
You’ll come across many chests and treasures as well so be on the lookout.
Deep within these dungeons you may also find a shrine that may or may not spawn a boss mob. You could simply end up with another chest with better treasure to loot.
