You brandish the weapon used in the spell’s casting and make a melee attack with it against one creature within 5 feet of you. On a hit, the target suffers the weapon attack’s normal effects and takes 1d4 extra damage of they type associated with your deity or patron. If your deity or patron has no damage type associated with them, select radiant or necrotic as you see fit.
