These Now SI .. used to do silks quests and hunt named here and just invis at zone in and run to camp spot .. now you gotta fight your way through.. 2 of these sat at zin and both aggro invis
While hunting in Lavaspinners, had these cast or proc these spells on my 62 Warrior. Seemed that each one had a different spell to cast.
One of them is Black Cyclone: With all Offensive stats for level 62 maxed, and 220 DEX, I missed hitting this thing 99% of the time while this spell was on me. 6 casts of RLC did not remove it either. I just kept hitting berate to keep agro while Druid nuked it. After druid buffed Magic save to 201, spell landed, may be, 1 out of 15 casts.
The other is Stone Pummel:
Long lasting stun, didn't do much damage tho.
These were hunted near the entrance of Lavapinners and all conned DB to 62 Warrior and 65 Druid.
