Tiny Tina’s Wonderlands: How to complete the Clerical Error side quest

Trystrom has completely abandoned his belief in the gods. Because he is a cleric, this is a serious problem. Fortunately, he knows of a nearby shrine that has sacred literature. Anyone who reads these writings is supposed to have their faith restored. Surely, this will assist. If not, he can always find another means to recover his faith. Here's how to finish Tiny Tina's Wonderlands' Clerical Error side quest.

Trystrom may be found near the entrance to Crackmast Cove in the Overworld. You must complete the Ballad of Bones quest and have the Overworld section past Wargtooth Shallows unlocked in order to access this location. Go down the slope and turn left from Wargtooth Shallows. Trystrom may be found at the top of the hill if you go up the hill.

Trystrom will take you toward a local temple where you can obtain the sacred scriptures. To get to the Temple of Faith, go down the hill and under the invisible bridge. You've arrived at the dungeon. Inside, you'll face two waves of attackers to overcome. Coiled will be the first wave, while Seawargs will be the second. The sacred writings will be obtained from the reward chest if you complete the second wave. Return the sacred writings to Trystrom to complete the mission.
