Notes
- Corrupted Zunraa appears once you clear the last of the miasma from the temple, so be on guard.
- Its skills are very devastating to melee fighters, and it is a very capable healer. High damage output and conditioning are advised to make the fight easier.
- An Unwelcome Guest ends after defeating Corrupted Zunraa.

Bug.
