Divine Weapon

You channel divine power into your weapon. The next creature you hit this turn with a melee weapon attack takes extra damage equal to 1d8 + your spellcasting ability modifier. The extra damage is necrotic or radiant; you choose the type of damage when you cast this spell. Until the spell ends, you can use a bonus action on each of your subsequent turns to channel divine power into your weapon again.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for every two slot levels above 2nd.
