Super: Hammer of Sol

As an action, you can temporarily harness the sun's energy in the form of weaponry.

A small, flaming hammer appears in your hand. As a bonus action, you can throw this hammer at a target. Make a ranged attack against the target, dealing 4d10 fire damage on a hit. When the hammer hits a surface or creature, it immediately returns to your hand.

This hammer can be wielded for a number of turns equal to your proficiency bonus, and vanishes afterwards.

You can't use this feature again until you finish a long rest.
