There are 7 boss dungeons hidden throughout Tiny Tina’s Wonderlands‘ Overworld. You need to defeat each of the bosses inside in order to unlock the Dungeon Ender! achievement and these dungeons also contain Shrine Pieces that will give you a permanent passive boost.
These boss dungeons consist of three maps, two where you need to defeat a wave of enemies and a final obelisk room that features a mini-boss.
The mini-bosses in these Overworld Dungeons also drop dedicated legendary weapons, however, this problem I always run into is, which overworld boss is hidden where on the map. That is where this guide comes in. I’ll be sharing where you can find each boss and what items they have in their loot pool, so you know where and who to farm.
