Tesla Coil

Deal 3 damage. Trigger all Lightning against the enemy.

Tesla Coil is an uncommon Defect attack costing 0 Energy that deals 3 damage and triggers all Lightning Orbs against the targeted enemy. This zero-cost card effectively converts your entire Lightning board into immediate focused damage, making it devastating when you have multiple Lightning Orbs channeled.

Tesla Coil pairs perfectly with Electrodynamics, which makes the triggered Lightning hit ALL enemies. Ball Lightning and Zap fill your board with Lightning Orbs for Tesla Coil to trigger. Thunder adds bonus damage per Lightning Evoke, and Storm generates Lightning through Power plays that Tesla Coil then weaponizes.

For the Defect, Tesla Coil is a free burst damage tool that scales with your Lightning board. Against bosses like Knowledge Demon, triggering 3-4 Lightning Orbs for 0 Energy can deal massive damage. Against Ceremonial Beast with Electrodynamics, Tesla Coil wipes the board. Pick Tesla Coil in Lightning-heavy builds where you consistently have 2+ Lightning Orbs channeled.
