Root locked at SoG, dead in seconds. Couldn't move from the first hit of SoG. Checking logs files indicate nearly every SoG hit was aoe, or multi hits.

Blight Brambles is 2 hits per person.

Blighted Brambles - AOE
Life void - AOE
Whirlwind attack - AOE
again he hits with blighted brambles - AOE
again hits with Life Void - AOE

Son's Shield used Kwellen Errupt - AOE
At this point I am already dead.

mind you this is all within about 10 seconds of the first hit to pull him in
soon as I am revived, it starts all over:
Gaping Void - AOE
Blighted Brambles.....
dual hits by Son's shield for Kwellen Errupt V -AOE
Paralizing Gaze - AOE

More dual hit AOE's from SOG
Son of Gigaroth hit you with Gaping Void for 263 blight damage.
Son of Gigaroth hit you with Gaping Void for 336 blight damage.
Also the rest of the group members

Does he or his shields do any single hits anymore? I fought him around christmas and it was not constant AOE's nor was it that easy for him to kill me. within 2 minutes the entire team was down.

He can hit 5 people before anyone can hit him, just using his normal attack. Once again I have to assume this attack is AOE. All it said was hits you for blight damage.. hits xxx for blight damage and so on. no skill or any name used for this attack
