Thunder Strike

Thunder Strike is a rare Defect attack costing 3 Energy that deals 7 damage to a random enemy for each Lightning Orb channeled during the entire combat. This scaling mechanic means Thunder Strike grows stronger with every Lightning channel, becoming a devastating finisher that can deal 50-100+ damage in Lightning-focused runs.

Thunder Strike scales with every card that channels Lightning: Zap, Ball Lightning, Lightning Rod, and Storm all increase its hit count. Electrodynamics provides 2 Lightning channels on play and makes subsequent Lightning AoE. Cold Snap and Rainbow each contribute to the Lightning count while providing other benefits.

For the Defect, Thunder Strike is the ultimate finisher in Lightning builds. Against multi-enemy bosses like Ceremonial Beast, each hit of Thunder Strike picks a random enemy, naturally distributing damage. Against single targets like Doormaker, all hits focus on one enemy for massive burst. Build up Lightning channels throughout the fight with cheap channelers, then drop Thunder Strike for a devastating finale. Pair with Electrodynamics for the best results.
