The Storms Rage

Thunderous anger builds up inside you, waiting for release, as a magic Action you activate the Rage, giving you resistance to thunder and lightning damage and Immunity to being deafened for one minute.

You call a thunder strike from the sky hitting one creature in range for 3D10  thunder damage, once per turn after as a bonus action you can call on the thunder to strike the same target again, each time the creature must roll a Dexterity saving throw, on a save taking half damage. 

This ability can be reused after being extended by burning a spell slot, every spell slot above level 1 add 1 D10 extra damage.

This ability can also be effected by class traits like scorcer points or channel divinitys.
