Elemental Rebound

You attempt captures the incoming energy, storing it for yourself. Roll 4d10; the total is how much you capture, reducing the damage of the spell damage by that amount. You can, as an action, redirect the energy out back in a 30ft cone for fire or cold damage, and a 60ft line for lighting and acid damage. When the spell ends or if your concentration is broken, while still storing energy, you take the damage as if you where vulnerable to the damage type. This damage ignores resistances.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, roll an additional 1d10 for each slot level above 3rd.
