I built a PvP Wizard that focuses on slowing the enemy.
Changed Hydra to Arcane Hydra so that its missiles will slow enemies by 30% via Temporal Flux
Using Seeker Missile to keep enemys slowed when running/attacking
Slow Time and Comet are for AoE slow, with Comet dealing massive damage
Disentigrate for while enemies are in the Slow Time bubble or in Comets AOE
Teleport to escape slowed enemies
I would use some more frost and slow, but then you'll need a high dps arena partner.
Well, every bolt from Arcane Hydra that hits will slow target by 30% for 3 seconds, as well as the Seeker Missile. Then Comet and Slow Time for huge AOE slows, I think they'll be slowed the majority of the time.
I think you need illusionist. a lot of characters have abilities to limit the distance between themselves and ranged wizards. teleport CD will be really essential for survival. Meh, I guess it depends if you are super glass cannon role with your partner or survivalbility. Nice ice build though, I have the same idea as well.
