Corellon’s Sacred Weapon

The longsword you are holding is imbued with Corellon Larethian’s holy 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. The sword’s damage die increases to d10 and becomes magical, if it isn’t already. The spell ends if you cast it again or if you let go of the weapon.
