Circle of Storms Shillelagh

The wood of a club or quarterstaff you are holding is imbued with nature's 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 spell ends if you cast it again or if you let go of the weapon.

When you choose this circle at 2nd level, you can imbue a weapon with ancient storm magic. You learn the shillelagh cantrip. When you cast it, you gain additional benefits:

• The duration is 24 hours, instead of 1 minute.
• While holding the weapon, you gain a +1 bonus to AC. This increases to +2 at 10th level.
