SQ Razor Sharp
Crimson Roar (Su)
A crystal dragon lets loose a ferocious roar that affects allies within 30 feet. Affected creatures gain a morale bonus to damage rolls equal to crystal dragon’s Charisma modifier for 1d6 rounds. Blue mages may learn this ability as a 4th level spell (Knowledge: Arcana DC 23).
Dragon Force (Su)
A crystal dragon releases the dragon soul within, improving itself or an ally by touch. This ability grants the subject an increase to all physical damage, melee and range, by +1 per three caster levels. It also grants the subject an increase to all magical damage and healing by +1 per three caster levels. This ability lasts for a minute. Blue mages may learn this ability as an 8th level spell (Knowledge: Arcana DC 31).
Heaven’s Cataract (Su)
Once every 1d3 rounds as a standard action, a crystal dragon creates an eerie sound affecting anyone within a 30-ft. radius from her. Those caught in the eerie waves takes 12d4 points of non-elemental damage and must make a Will save (DC 31) to negate the status effect and reduce the damage by half. The status effect reduces all enemies’ resistance to saving throws versus spells by 2 and deflection bonus to Armor Class by 2 for 1d6 rounds. Anyone that cannot hear is immune to this effect. Blue mages may learn this ability as a 6th level spell (Knowledge: Arcana DC 27).
Once every 1d2 rounds as a standard action, with a great, heaving breath does the crystal dragon belch forth a cloud of noxious mist. As a standard action, the crystal dragon deals 5d6 non-elemental damage to all enemies in a 30 ft. cone; a successful Reflex save (DC 31) halves this damage. All enemies within the area of effect who failed the Reflex save must make a series of saves (DC 31) to avoid each of the following effects: Disease (Fort), Silence (Will), Sap (Fort), and Slow (Will), all of which last for 1d8 rounds. The crystal dragon must wait 1d4 rounds before using this ability again. Blue mages may learn this ability as a 5th-level spell (Knowledge: Arcana DC 25).
Mighty Roar (Su)
Once every 1d4 rounds as a standard action, the crystal dragon brings out a mighty roar. Any creature within the area is deafened for 6d6 rounds, stunned for 1 round, and takes 15d6 points of non-elemental damage. Any exposed brittle or crystalline object or crystalline creature takes 1d6 points of non-elemental damage per caster level (maximum 20d6). A creature in the area of the cone can negate the stunning and halve both the damage and the duration of the deafness with a successful Fortitude save (DC 31). A creature holding vulnerable objects can attempt a Reflex save to negate the damage to those objects. Blue mages may learn this ability as a 8th level spell (Knowledge: Arcana DC 31).
Razor Sharp (Ex)
All of a crystal dragon’s natural attacks deal slashing damage.
Scintillating Aura (Su)
A crystal dragon radiates an aura of scintillating color from its jeweled scales to a radius of 60 feet. All within this area must make a Will save each round to avoid being stunned (if the victim has 15 or fewer Hit Dice) or confused (if the victim has more than 15 Hit Dice) for 1 round. The save DC is equal to the dragon’s breath weapon save DC. This is a mind-affecting effect. The dragon can activate or suppress this aura as a free action.
