So, this is what I gathered from these posts:
1. Kill everything in zone, starting with named. Eastern half of the zone is on a 12 hour spawn timer, the western half is 15 minute
2. Attach cats in her room to get her to gate.
3. After being aggro'd, she respawns at +1600 -250 in a large open area. If not engaged in about 15 minutes, returns to tree
4. Get on mount to avoid knockbacks and spell interupts
5. Perma root can be removed with radiant cure
6. The first 70% HPs go off her easy, but the last 30% takes longer due to mobs healing her
7. Finally, use /tar tunare's corpse (this didn't work for me but it doesn't matter with /advloot)
