Static Cantrip
Whenever you deal Lightning damage to an enemy with a Warmage cantrip, you can sap part of the energy into a charge, which clings to your body until the start of your next turn. While charged, you can take a Reaction in response to taking damage from a creature you can see within 5 feet of you to deal Lightning damage equal to half your Warmage level to the creature.
