Signs: Aard

You gain the ability to harness the primal forces of nature around you and convert them into arcane energies through the use of powerful signs. You use your INT when determining your spell attack bonuses and spell save DC's. Your spell save DC is equal to 8 + your proficiency bonus + your INT modifier. Using a sign during combat counts as an action on your turn. You have a number of Vigor points equal to your CON modifier + your proficiency bonus. Each use of a sign expends 1 vigor point. You regain 1/2 of your expended vigor (rounded down) whenever you complete a short rest and regain all expended vigor during a long rest. The signs you know and can use are determined based upon which Witcher School you belong to. This ability replaces the Rangers ability to cast spells normally.
