Blessed Hammer

The Weapon you are holding is imbued with divine power. For the duration, you can use your spellcasting ability instead of Strength for the attack and damage rolls of melee attacks using that weapon, and the weapon's damage die becomes a d8. The weapon also becomes magical, if it isn't already. The weapon's other magical properties is still applied. 

The spell ends if you cast it again or if you let go of the weapon.

Damage dealt by a weapon attack using this cantrip is not considered as damage dealt by a cleric cantrip.
