Shillelagh

The wood of your weapon is imbued with nature's power.

Target. One club or quarterstaff you are holding.

Effect. 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.

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

Cantrip Progression. This spell improves in certain ways when you reach higher levels. At 5th level, you can cast this spell on any weapon, changing the die to a d8 only if it is not already higher. At 11th level, the weapon's damage die becomes a d10 if it not already higher, and at 17th level, the weapon's damage die becomes a d12 if it is not already higher. At 23rd level, the spell no longer ends if you use it again, though it does end if you let go of the weapon. At 28th level, the duration becomes 1 hour.
