Abyssal Pressure

Choose one creature within range that is wet, underwater, or within 10 ft. of water. The target must make a CON save, taking 66 (12d10) bludgeoning damage and becoming restrained until the end of its next turn on a failed save, or half damage with no restraint on a success.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
