Hailstorm

Hailstorm is an uncommon Defect Power costing 1 Energy that deals 6 damage to ALL enemies at the end of your turn if you have any Frost Orbs channeled. This passive AoE damage adds offensive capability to Frost-based defensive builds, allowing you to deal damage while focusing on Block generation.

Hailstorm pairs naturally with Glacier and Coolheaded, which channel Frost to satisfy the condition while providing Block. Defragment boosts Frost passive Block while Hailstorm adds the damage component. Cold Snap channels Frost while dealing direct damage, and Chill channels Frost for each enemy for guaranteed multi-target Hailstorm triggers.

For the Defect, Hailstorm turns Frost defensive builds into something that can also kill enemies. Against bosses like Ceremonial Beast and Kin Priest with multiple enemies, the end-of-turn AoE chips everything down. Against single-target bosses like Vantom, 6 damage per turn adds up alongside Frost's defensive value. Pick Hailstorm when your deck already generates Frost reliably and needs a passive damage source.
