Void Maelstrom

Void Maelstrom is an X-cost Void Epic dealing 5 damage X times, applying 1 Vulnerable and 1 Hex, with Exhaust. Dumping all energy creates multiple hits that each benefit from Mark and Strength bonuses. Level 3 adds +1 Hex, and level 5 adds +1 Vulnerable.

Vulnerable makes the enemy take x1.5 damage, amplifying all subsequent attacks and damage-over-time. The Hex generates Poison on future damage. Energy fueling from Void Exchange, Foresight, and Purifying Flame maximizes hit count.

The Exhaust triggers Feel No Pain, Dark Harvest, Soul Collector, and Phoenix Feather. Crystal of Duality adds +3 Block. The combination of Vulnerable and Hex creates devastating follow-up potential.

Enhanced versions get x1.2 per hit. Best as a setup card in Void combo builds that want to debuff before a finishing burst.
