"I call upon the mighty earth to encompass thy strength and become my shield!"

You surround a unarmoured willing creature with a protective magickal force.

For the duration, the creature's AC is equal to 13 + their DEX modifier. The spell ends if the target dons armour or if you dismiss the spell as an action.
