Outer dragons, natives of the vast reaches of space, can be encountered on diverse worlds. They are generally neutral, but their alignments vary more than those of other dragons.
As a dragon ages, it goes through 12 age categories. Its base statistics change as noted on Table: Dragon Age Categories.
Age Category: This is the age category’s name.
Age in Years: This is the dragon’s actual age.
CR: This column modifies the dragon’s base CR.
Size: This column shows the number of size categories by which to increase the dragon’s base size, depending on its age. Instead of the standard increases to ability scores when it achieves a larger size, a true dragon gains ability score increases according to its age category, as indicated on Table: Dragon Ability Scores.
Hit Dice: This shows how many Hit Dice a dragon gains over its base Hit Dice as it grows. Increases to Hit Dice grant extra hit points, feats, and skill ranks as well as increasing base attack bonus and base save bonuses. Dragons have skill ranks equal to 6 + their Intelligence modifier per Hit Die. A dragon’s increases to ability scores for gaining Hit Dice are included in the totals on Table: Dragon Ability Scores.
Natural Armor: This shows the amount the dragon’s base natural armor bonus increases with each age category.
Breath Weapon: Each dragon has a breath weapon that deals a base amount of damage. This multiplier increases the number of dice of damage dealt. For example, a mature adult with a base breath weapon that deals 2d6 acid damage would deal 14d6 acid damage (due to the ×7 multiplier).
Table: Dragon Attacks and Speeds lists attacks a dragon can employ and the damage it deals (a dash indicates a dragon of that size doesn’t possess that attack). Dragons gain other abilities listed here at specific age categories.
Fly Speed: A dragon’s fly speed increases based on its size.
Bite: This is a primary attack that deals the indicated damage plus 1-1/2 times the dragon’s Strength bonus (even though it has more than one attack). A dragon’s bite attack has reach as if the creature were one size category larger (+10 feet for Colossal dragons).
Claws: These primary attacks deal the indicated damage plus the dragon’s Strength bonus.
Tail Slap: The dragon can slap one foe each round with its tail. A tail slap is a secondary attack that deals the indicated damage plus 1-1/2 times the dragon’s Strength bonus (this is an exception to the normal secondary attack rules).
Wings: The dragon can slam foes with its wings, even when flying. Wing attacks are secondary attacks that deal the indicated damage plus 1/2 the dragon’s Strength bonus.
A flying or jumping Huge or larger dragon can land on foes as a standard action, using its body to crush any of them that are three or more size categories smaller than the dragon. A crush attack affects as many creatures as fit in the dragon’s space. Creatures in the affected area must succeed at a Reflex save (DC equal to that of the dragon’s breath weapon) or be pinned, automatically taking bludgeoning damage during the next round unless the dragon moves off them. If the dragon chooses to maintain the pin, it must succeed at a combat maneuver check as normal. Pinned foes take damage from the crush each round if they don’t escape. A crush attack deals the indicated damage plus 1 -1/2 times the dragon’s Strength bonus.
A Gargantuan or larger dragon can sweep its tail as a standard action. The sweep affects a half-circle with a radius of 30 feet (or 40 feet for a Colossal dragon), extending from an intersection on the edge of the dragon’s space in any direction. Creatures within the swept area are affected if they are four or more size categories smaller than the dragon. A tail sweep automatically deals the indicated damage plus 1-1/2 times the dragon’s Strength bonus (round down). Affected creatures can attempt Reflex saves to take half damage (DC equal to that of the dragon’s breath weapon).
Using a breath weapon is a standard action. A dragon can use its breath weapon once every 1d4 rounds, even if it possesses more than one breath weapon. A breath weapon always starts at an intersection adjacent to the dragon and extends in a direction of the dragon’s choice. Breath weapons come in two shapes, lines and cones, whose areas vary with the dragon’s size. If a breath weapon deals damage, those caught in the area can attempt Reflex saves to take half damage. The save DC against a breath weapon is 10 + 1/2 the dragon’s HD + the dragon’s Constitution modifier. Saves against various breath weapons use the same DC; the type of saving throw is noted in the variety descriptions. A dragon can use its breath weapon when it is grappling or being grappled.
A juvenile or older outer dragon has an aura that functions as frightful presence with a range equal to 30 feet × the dragon’s age category. The effect of each dragon’s alien presence is noted in its description.
Every dragon is immune to sleep and paralysis. In addition, a dragon is immune to additional forms of attack, as given in its description.
Outer dragons don’t need to breathe and are immune to inhaled poisons, suffocation, and drowning. See the universal monster rules for more information.
Outer dragons can see perfectly in darkness, even that created by deeper darkness.
As dragons grow older, they become more resistant to spells and spell-like abilities, as indicated in their descriptions. A dragon’s SR is equal to 11 + its CR.
In outer space, an outer dragon can survive in the void and fly at incredible speed. Travel times vary, but a trip within a single solar system should take 3d20 hours, and a trip beyond should take 3d20 days or more if the dragon knows the way to its destination. An outer dragon can carry one rider of one size category smaller than itself, four passengers two sizes smaller, eight passengers three sizes smaller, or 16 passengers four or more sizes smaller. Passengers are protected from the void of outer space.
