You have a lightning-generating Power Cell that you can use to empower your equipment. If your cell is ever lost or damaged, you can repair or replace it over the course of a Long Rest using materials worth 100+ GP. While carrying your Power Cell, you gain the following benefits.
Charge Points
Your Power Cell gives you a number of Charge Points equal to your Craftsman level. You regain all expended Charge Points when you finish a Long Rest.
Shock
Once on each of your turns when you deal Lightning damage, you can expend a number of Charge Points up to your Proficiency Bonus to deal extra Lightning damage. The extra damage equals 1d6 for each Charge Point expended plus your Intelligence modifier.
Lightning Resistance
You have Resistance to Lightning damage.
Lightning Weapons
When you deal damage with a weapon, it can deal your choice of Lightning damage or its normal damage type.
