|As you become an expert at the lore of frost, you gain the ability to create and project large amounts of stable null point energy and force it to create more complicated shapes.|
|As an action you can spray an area with supercooled air, rapidly forming blocks of ice that grow into a thick wall. You choose up to six adjacent square meters in range. A pillar of ice, up to 3 meters tall, grows in the selected area. You pay 3 Vitality for every pillar you create.|
Every pillar has 100 hit points, is invulnerable to necrotic and psychic damage, resistant to piercing and slashing damage, and vulnerable to fire damage. Cold damage heals it instead.
Creatures in the wall’s space when it is created are moved to an adjacent space of their choice.
