Storm

Whenever you play a Power, Channel 1 Lightning.

Storm is an uncommon Defect Power costing 1 Energy that channels 1 Lightning Orb whenever you play a Power card. In Power-heavy builds, Storm generates massive Lightning accumulation over the course of a fight, turning every utility Power you play into additional offensive pressure.

Storm synergizes exceptionally with Creative AI, which generates a Power each turn that triggers Storm's Lightning channel. Subroutine grants Energy for each Power played alongside Storm's Lightning, and Electrodynamics makes all that Lightning hit ALL enemies. Thunder deals bonus damage on every Lightning Evoke generated by Storm.

For the Defect, Storm is a key connector between Power-based strategies and Lightning damage. Against multi-enemy bosses like Ceremonial Beast, Storm with Electrodynamics creates a constant AoE barrage. Against Kaiser Crab, the Lightning accumulation from playing Powers builds toward a massive Thunder Strike finisher. Prioritize Storm in decks with many Powers, especially alongside Creative AI for guaranteed Lightning each turn.
