that's just a normal blizzard sorc..? I don't see why is it suicide... a suicide chararcter is a characer with many facet, once they die, they bring down thier enemy with the die facet.

From you buid... you just making a blizzard sorc, when a melee character come near you and try to MELEE you with close rang, you cast blizzard on yoursef, so if they come near, they die.
