Description

Young sea dragons are light bluish-gray, darkening to deep slate in older individuals. Their bodies are compact, sleek, and smooth, with webbed feet and short, broad tails built for swimming rather than walking.

Sea dragons breathe air like dolphins or whales. A sea dragon can hold its breath for up to three turns while swimming or performing other moderate activity, and often keeps its lair in an air-filled undersea cavern.

The breath weapon is a cloud of scalding steam. A typical adult cloud is about 40 feet across; younger or older specimens may range from about 25 to 55 feet across. Sea dragons are immune to ordinary steam and suffer only half damage from magical steam.

Use the normal White Box dragon age rule for hit points and breath damage. The breath weapon is usable three times per day, and a successful saving throw halves the damage.

Dragons

All dragons have a breath weapon of some kind, which can be used up to three times in a day. The Referee chooses when a dragon will use the breath weapon or may roll for it (50% chance) in any given round.

Referees should not roll for a dragon’s hit points, like one would for other monsters. Instead, determine the age category of the dragon—this will give both the dragon’s hit points per hit dice and how many points of breath weapon damage per hit dice the dragon inflicts.

For example, an “Adult” dragon has both 4 hit points and 4 points of breath weapon damage per hit dice. So an “Adult” black dragon with 6 HD would have 24 HP and deal 24 points of acid damage when using its breath weapon.

* The dimensions of a dragon’s breath differ according to the dragon’s type.

Note that dragons, while dangerous opponents, are not by any means invincible. In a medieval-type fantasy world, dragons are a common problem rather than a godlike creature of legend—so the statistics for dragons reflect a deadly but not mythical foe. The Referee is, of course, free to create stats for a more “mythical” conception of dragons. Since dice aren’t rolled for dragon hit points, it is possible for a truly mythical dragon to have more “numbers” per die than it’s actually possible to roll on a hit dice.
