Primordial Stage 2: Boon of Elemental Surge - Earth

You can channel pure elemental energy into a concentrated bolt of an element of your choice. As a Magic action, you can use any of the following option:

Earth Shard. You can force a creature within 30 feet to make a Constitution saving throw. On a failed save, the creature takes Bludgeoning damage equal to 3d6 plus your Constitution modifier, or half as much on a successful save. Increase the damage by 1d6 for each Transformation Stage above 2.

You also gain Temporary Hit Points equal to half the damage dealt.

You can use Elemental Surge a number of times equal to your Constitution modifier, regaining all expended uses upon finishing a Long Rest.
