Chaos Storm = Less Damage (1000), but leaves lava that would do 50% of the damage that the storm would have done if it connected. Tempest = More damage (1200), but no lava, so opponents can run back in to attack you when it's done much faster.
Well... It IS for a lvl30 so Each one of those is more than likely used for trolling purposes, except the few times i ast it and people rush in not knowing what it is. Do you think I should invest the point in attunement, rynn?
I'm on PC. Used to be on 360, then PS3. I think that's what I'll do, because my character is all about aesthetic appeal with a hefty dose of strength. c:
