The Fabled Maid Issis info...
Killed her with the assistance of a lvl 53 Druid, I am a lvl 62 Necro at he moment.
Druid dropped a couple of DoT's on her then focused on healing my pet. I too dropped a few DoT's and focused on healing my pet and twitching the druid.
Her run speed can't be changed.
She summons
She Enrages at around 10%
She casts Fear, Boiling Blood, Venom of the Snake, possibly more but that's all I noticed.
None of my spells were resisted by her except Dooming Darkness.
She spawns in the old orc camp, approx 400, 300. The Northern most orc camp on the EQ Atlas map.
Hope this helps
