This is designed to push the solo leaderboards. Save your resource until halfway through the arcane rotation of Convention of Elements. Move 40 yards away from your target. Cast black hole and dump all your blue balls. They should be exploding on your target, during the cold rotation of Convention of Elements. Make sure you have 4 Explosive Blast stacks and 3 Triumvirate stacks for maximum damage.
Damage reduction comes from Orb of Infinite Depth + Explosive Blast stacks (80%), Halo of Karini + Storm Armor proc (80%), and Slow Time Bubbles (60%). Make sure you keep all damage reduction buffs active at all times. Letting even one of these buffs drop can cause you to die immediately.
