This set of a warhammer and shield can be used in the place of a holy symbol, and can be sheathed in electricity at will to deal lightning damage in place of bludgeoning damage. You have a +1 bonus to attack and damage rolls made with the magic weapon. This weapon has 4 charges and regains 1d4 charges after a long rest. As a bonus action, a creature attuned to this set of magic items can expend a charge to activate one of the following effects:
Lightning Streak:
You can expend a charge to briefly transform into a streak of lightning. When you do, choose an unoccupied space you can see within 15 feet of you. You form a 5-foot-wide line of lightning originating from yourself that extends to the unoccupied space. You reappear in the next unoccupied space in that line as the streak of lightning passes through anything in its path. Make a spell attack against any creature within the line. On a hit, the creature takes 1d6 + 1 Lightning damage as you pierce through it as the bolt of lightning.
Lightning Jolt:
When a creature you can see hits you with a melee attack, you can expend 1 charge as a reaction to deal 2d4 lightning damage to the attacking creature. After the attack, you gain that same amount of lightning damage as temporary hit points that last for up to 1 minute as a jolt of electricity fills your body with a surge of adrenaline.
Proficiency with a Warhammer allows you to add your proficiency bonus to the attack roll for any attack you make with it.
This weapon has the following mastery property. To use this property, you must have a feature that lets you use it.
Push. If you hit a creature with this weapon, you can push the creature up to 10 feet straight away from yourself if it is Large or smaller.
