Thunder of Zavala

 You raise and ready your first as a charge of Arc power builds up within it, then as you thrust forth your hand, a bolt of Lightning shoots forth from your outstretched palm. Make a Melee Spell Attack extending your melee damage up to 15ft and dealing 2d6(SM) Lightning damage on a hit. Or, if you Expend your Action, your Bonus Action and your Movement Speed to Charge Up the attack and release it, then each creature in a 15-foot Cone must make a DEX Saving Throw. A creature takes 4d6(SM) Lightning damage on a failed Save, or half as much damage on a successful Save. You gain Lightning Resistance until the start of your next turn if you Charge Up in this way. 

*If you cast this spell as a Paladin you may choose to make it deal Radiant damage instead of Lightning.

*SM=Spellcasting Modifier.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
