Part 19: Exiguus and the Undead Bonus
You'd have to try pretty hard to finish this quest while still failing it. The exit doesn't unlock until you step on the river bridge down in the cavern area, and from there you're just two rooms away from Exiguus and the quest objective.
As for the sound quality, this video was recorded a while ago, but I did try a new mic when recording 5-1. We'll see how it turns out.
EDIT: POTIONS. I'll do a scrolls one tomorrow.
