Divine Weapon

You channel divine magic to create the melee weapon of your god, ready to deliver a powerful attack. Make a melee spell attack against one creature within 5 feet of you. On a hit, the target takes 1d8 radiant (or necrotic, if you worship an evil god) damage. After you make the attack, the weapon disappears. You have advantage on the attack roll if the target is a certain type of creature: aberration, celestial, elemental, fey, fiend, or undead.

After taking damage, you gain a ward of protection against the creature: it has disadvantage on attack rolls against you, and you have advantage on saving throws against effects created by that creature. This ward of protection lasts until the end of your next turn.

The spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
