SPECIAL ABILITIES

Desert Thirst (Su)

A blue dragon can cast create water at will (CL 24). Alternatively, it can destroy an equal amount of liquid in a 10-foot burst. Unattended liquids are instantly reduced to sand. Liquid-based magic items (such as potions) and items in a creature’s possession must succeed on a Will save (DC 29) or be destroyed.

Electricity Aura (Su)

An adult blue dragon is surrounded by an aura of electricity. Creatures within 10 feet take 2d6 points of electricity damage at the beginning of the dragon’s turn.

Mirage (Su)

An ancient blue dragon can make itself appear to be in two places at once as a free action for 24 rounds per day. This ability functions as project image but the dragon can use its breath weapon through the mirage.

Sound Imitation (Ex)

A very young or older blue dragon can mimic any voice or sound it has heard by making a successful Bluff check against a listener’s Sense Motive check.

Storm Breath (Su)

An ancient blue dragon can use its breath weapon to create a storm of lightning. This functions as call lightning storm, but the damage is 20d8. The dragon can call down 1 bolt per round as a free action for 1d6 rounds. The save DC is 29. Additional uses of this ability extend the duration by an additional 1d6 rounds.
