Large predatory fish that live in deep rivers and lakes
Giant gar live in deep rivers and lakes. They can swallow prey whole on an attack roll of 20, including creatures up to Man-sized. A swallowed person has a cumulative 5% chance per segment of drowning, but if he or she has a cutting weapon, may cut him- or herself free. To do so, 25% of the giant gar's total hp must be inflicted. Any piercing attack against a giant gar has a 20% chance of causing equal damage to a swallowed creature.
