Phixer already posted some information and I have something to add!Asaad
No Static at All
Difficulty: Easy (2)
"Completely avoid the Static Cling effect during the Asaad encounter in the Vortex Pinnacle on Heroic Difficulty".
SUPER easy if you have a priest in the group, just put levitate on people and the wont get it. If you dont have a priest you just have to jump about 1/3 into the cast of his Static Cling. If you do this you wont get the debuff and achi inc.
You only have to avoid the first and maybe the second Static Cling, when you have to run into the triangle which is summoned by Asaad stay outside and die, now stay dead until the boss dies.
The bad thing about this exploit is to have a 4 man grp which is strong enough to defeat this "strong" encounter
Good luck getting your Drake!
