An aquatic longbow is an underwater version of a longbow that is favored by aquatic elves. It typically weighs 3 lb (1.4 kg) and costs 400 gp, with a kelp string to dampen vibration. Unlike regular underwater weapons, the aquatic longbow does not suffer from range-related penalties. Mighty composite versions of the aquatic longbow range from 600 gp to 900 gp.
