Dawn Hammer

Light coalesces in your grip, creating a hammer of divine energy. (Spell Last for 5 Hours)

The magic hammer lasts until the spell ends. It counts as a simple melee weapon with which you are
proficient. It deals 2d8 radiant damage on a hit and has the light and thrown properties (range 20/60).

Creatures you hit with this weapon surrounded by holy light, making the next attack roll against this target before the end of your next turn have advantage. If you drop the weapon, it dissipates at the end of the turn.

Thereafter, while the spell persists, you can use a bonus action to cause the Hammer to reappear in your hand.
At Higher Level When you cast this spell using a 3rd-or 4th-level spell slot, the damage increases by 1d8
