Requirements A foe within Stone Ghost's reach is standing on stone or soil

Effect Stone Ghost briefly extends his intangibility to a foe and drags or pounds them into the earth. He makes an Athletics check against the target's Fortitude DC. On a success, the foe is planted waist-deep in the ground and is Immobilized and Off-Guard until it Escapes. On a critical success, the foe is completely buried and must hold its breath until it is free or else start suffocating. A successful Escape returns the foe to its original square on the surface, or the closest unoccupied square.
