Effect Two crew members each perform a 3-action activity on their turn to release a massive buildup of steam around the vehicle, dealing 11d6 fire damage to each creature in a 10-foot emanation (DC 35 basic Reflex save). The release mechanism stops working if the vehicle is broken.
Description This heavily armored aquatic vehicle resembles a gargantuan sea turtle covered with steel plates. The steam turtle is designed for beach landings and assaults on port facilities. Once it disables enemy fortifications, it extends a long boarding gangplank for troops to disembark and deploy.
