Challenge Accepted achievement in Tiny Tina's Assault on Dragon Keep: A Wonderlands One-shot Adventure
Note that the description says that you do not need to do the level-specific achievements (like finding the vault symbols on each level). You only need the general, global challenges.
All challenges only need to be completed to level 1 (again, except for the ones that require level 5, which I unfortunately don't remember). Leave a comment if you see a challenge that needs to be level 5 to unlock another one.
Shout out to The Cherished for compiling the original list.
