Bright's Blade

Pulling from both the Sorcerer's power to render objects from magic and the divine power present in the Divine Soul. The caster coalesces a sword of pure radiant energy. 

You are proficient in its use and are able to make melee spell and ranged spell attacks with it( out to 90ft). The ranged attack is throwing the blade. It's dissipates at the end of your turn if it is not in you hand at the end of your turn, but as long as you are maintaining the spell you can recreate it as a bonus action.

Any target struck with it is surrounded by a mystical dim light granting advantage to the next attack made against them until the end of your next turn.

It sheds bright light in a 20ft radius and dim light for another 20 ft, this does not penetrate or dispell magical darkness, as it is a byproduct not a primary function of this spell.

It deals 3d8 plus spell modifier radiant damage on a successful attack.

It deals an extra 1d8 for every 2 levels above the 3rd
