Prerequisite: Requires an AC calculation using an ability score
You have grown into a reliable protector, willing to give up your own defensive position to defend nearby allies.
You increase your Dexterity, Constitution, or Wisdom by 1, to a maximum of 20.
When a creature within your reach is hit with a weapon attack, you may freely donate the ability score used in your AC calculation until your next turn, adding your ability score to the target's AC and removing it from your own. This effect lasts until the beginning of your next turn or until you take damage by a weapon attack, following which you my choose to end the effect.
