Voltaic Armor

When you cast this spell as an action, lighting arcs all around your body, defending you against attacks. But leaving you extremely vulnerable to water.

You have resistance against all non-magical attacks, and immunity to lightning damage while this spell is active. (this does not apply to inherent class abilities like Wild Shape and Channel Divinity)

All attacks made by you deal 1d4 additional lightning damage, and you have advantage on grapple checks.

You are unable to cast any non-lightning-related spells while this spell is active.

Your speed is also increased by 10 feet while this spell is active.

Any direct contact with another creature deals 1d4 Lightning damage to the other creature. (This does not apply to contact through weapons)

Any amount of conductive fluid that touches you greater than 1 gallon deals 1d6  lightning damage to you, adding an additional d6 for each successive gallon after the first. I’d you were to ever be completely submerged while this spell is active, you would die instantly. (Damage dealt in this way surpasses the lightning immunity)
