Here is the full list of all 10 Dungeon Souls achievements.
Get killed by a Boulder Trap
Skeleton King is not worthy of being a king. Maybe I should start calling him SkeLOSER! (Kill the Skeleton King under 30 seconds without taking damage)
You've found all the heroes trapped in the dungeon.
Found all arcane forge recipes in the game and have at least one of each ingredient.
Something tells me I shouldn’t have picked more than 5 cursed items…
Maybe with 1 million gold I can buy a dungeon for myself!
Now I should know how to survive this hell of a dungeon! (Finish the tutorial)
The architect who built this dungeon must be amazing. 30 floors in and still no end in sight! (Reach a dungeon level of 30 floors or greater)
Is this the best that you can do?! 500 enemies are NOTHING! (Kill over 500 enemies on a single run)
We did it… We’re finally free… (Finish the story of the game, freeing all souls of the dungeon and defeating Selene one last time)
