Thunder

DefectPowerUncommon
Whenever you Evoke Lightning, deal 6 damage to each enemy hit.
  • A 1 Energy Power: whenever one of your Lightning orbs Evokes, every enemy it hit takes 6 extra damage, 8 upgraded.
  • The bonus is a separate unpowered hit, so Focus, Strength, Vulnerable and Weak do not change it, but it stacks if you play a second copy.
  • Automatic Evokes count, including the ones that happen when a Channel overflows a full board, while passives such as Tesla Coil do not.

When to take Thunder

Take it once your deck can Evoke Lightning several times a turn, since a single orb per turn does not justify a Power in Act 1. Strong with Dualcast or Multi-Cast.
