Touch Down [Reaction]

Routine (3 actions) The cyclone uses 3 actions to move, traveling up to 30 feet with each action and dealing 2d12+13 slashing damage to each creature in its path (DC 33 basic Reflex save). A creature needs to attempt only one save during the cyclone's movement, even if the cyclone moves over its space more than once. On a critical failure, a creature is swept up into the cyclone, becoming grabbed (Escape DC 33).
