Breath Weapon (Su): A tome dragon's breath weapon is weak (compared to other dragons), but very adaptable. Tome dragons can accurately spit a small bead of raw elemental material great distances (as far as a dragon's line breath weapon can extend), which then explodes in a manner similar to a fireball (blast radius equals 5 feet per age category). While the amount of damage remains the same no matter which element is used, the type of damage varies: a blast of air deals sonic damage, earth deals piercing damage, water deals nonlethal bludgeoning damage, and fire deals fire damage.
Free Metamagic (Su): Metamagic comes naturally to tome dragons. Applying a metamagic feat to a spell takes no extra time for a tome dragon (rather than increasing casting time to a full-round action or adding another full-round action, as normal for sorcerers). In addition, tome dragons can subtract the amount based on their age category from the increase in spell level caused by using metamagic feats. The number listed is the total reduction in extra spell levels, not the reduction for each feat applied (so a tome dragon with two levels of free metamagic would still add three levels to the cost of an empowered, maximized spell). This bonus can be applied to only one spell per round (additional spells cast in a single round are unaffected).
Other Spell-Like Abilities: At will - arcane sight, 3/day - clairaudience/clairvoyance; 1/day - plane shift.
This subtype usually is used for elementals and outsiders with a connection to the Elemental Plane Air. Air creatures always have fly speeds and usually have perfect maneuverability (see the section on Movement).
