Lightning Rod

Gain 4 Block. At the start of the next 2 turns, Channel 1 Lightning.

Lightning Rod is a common Defect skill costing 1 Energy that gains 4 Block and channels 1 Lightning Orb at the start of each of the next 2 turns. This delayed Lightning generation provides sustained Orb income over multiple turns from a single card play, making it one of the most efficient common cards for building up a Lightning board.

Lightning Rod pairs excellently with Electrodynamics to make the delayed Lightning channels hit ALL enemies, and with Thunder to deal bonus damage on each Lightning Evoke. Storm adds even more Lightning generation when Powers are played, and Thunder Strike scales its damage based on total Lightning channeled this combat.

For the Defect, Lightning Rod is a reliable way to build Lightning momentum without heavy Energy investment. Against multi-enemy bosses like Ceremonial Beast, the sustained Lightning channeling provides ongoing AoE pressure. Against single-target bosses like Knowledge Demon, the combination of Block and Lightning sets up future burst turns with Dualcast or Multi-Cast. Pick Lightning Rod early for consistent Orb generation.
