The ultimate team player. This build is focused around debuffing your foes, buffing your allies, and keeping everyone topped off on health while doing some decent single-target damage. You have 100% uptime on Cleaving Roar's debuff when you combine it with Ray of Destruction. Together with Great Fury and Time for Punishment, you greatly increase your party's damage output. Your curses should be constantly spammed. If you can time Curse Explosion to happen as soon as they're reapplied it does more damage. With the debuff combo and curses being spammy but simple to manage, it gives you tons of time to heal your team. Use your wand in your main hand in melee range to apply Cleaving Roar and increase its uptime and your overall damage.
Change out Annihilation Slash for Witty Strike for more mana, or Blessing of Immortality/Invincible Wall for more team support.
