Chaos Volley used to ramp up in damage and also damage done to the sorc; if you didn't cast after a certain period of time the ramp up restarted. As it continued to go higher you basically 1 shot yourself and died so the difference between average and good sorc's was maximing damage and coordinating with healers for mass heals/invuls etc. I ran my own 2 box healers for additional assistance when Turbo the sorc went into overdrive and liked to 1 shot himself....my fondest early game memory was I think the server first kill on prince in the low 40's sky fortress (fucking name escapes me now sad face). I had 2 shaman's with timing invul's on me so I was melting him so bad, I think my last hit on him stayed the top damage reported for a long time until more people caught on to how insane you could get with well coordinated efforts. More often then not though sorc's died so much because of this spell haha,
Oh god VG had the best classes of any MMO bar none. Also if I have to kite another SoD group ever again I may slit my wrists....
