Notes

Issk side of the Tunnels, dominated by Slithis, Virindi and Shadows, and Elementals of course.
Using the Decanter of Nullified Essence on the Stone of Yanshi and defeating the Reflection of the Harbinger reverts the tunnels to the version without the portals (see Weakened Harbinger Quest). Once you flag for the old tunnels, the original Harbinger is found at the end of the dungeon.
