By increasing the recharge time by 1 round can choose to for it to deal additional damage in the next round to all creatures and objects affected by it. This additional damage is equal to half the damage the breath weapon dealt to that creature or object. A second save is not allowed, but any creature or object that avoided all damage from the breath weapon in the first round (such as from evasion) does not take any extra damage. As a full-round action, a targeted creature can attempt a Reflex save (using the breath weapon's original save DC) to remove the clinging breath weapon and negate further damage. Rolling around on the ground grants a +2 bonus on this save.
Anklet of Translocation: 2/day as an swift action teleport 10 feet.
Crush: if flying or jumping, land on opponents as a standard action, using its whole body to crush them. Area 20 feet by 20 feet, small or smaller opponents take 2d8+19 points of bludgeoning damage, and must succeed on a DC 36 Reflex save or be pinned.
Spellcaster Harrier: Any spellcaster you threaten in melee provokes an attack of opportunity if he or she tries to cast defensively. You get a +4 bonus on this attack roll.
Combat Reflexes: Can make up to 4 Attacks of opportunity per round, can make attacks of opportunity even if flatfooted.
Hover: If a creature of Large size or larger hovers within 20 feet of the ground in an area with lots of loose debris, the draft from its wings creates a hemispherical cloud with a radius of 60 feet. The winds so generated can snuff torches, small campfires, exposed lanterns, and other small, open flames of non-magical origin. Clear vision within the cloud is limited to 10 feet. Creatures have concealment at 15 to 20 feet (20% miss chance). At 25 feet or more, creatures have total concealment (50% miss chance, and opponents cannot use sight to locate the creature).
Those caught in the cloud must succeed on a Concentration check (DC 20) to cast a spell.

The Ancient Blue Dragon commands a powerful arsenal abilities.
Daily, Hallucinatory Terrain and Veil allows her to disguise her surroundings, while Charm Monster and Dominate Person allow her to gather minions to serve as guards, distraction or support as needed.
Contigency can prepare one spell beforehand, usually Scintillating Scales with the trigger being an enemy targeting you with a touch attack of some sort.
Polymorph can be used to hide her true form when she wants to blend in.
Enervation provides an alternate attack option most enemies won't expect from a Black Dragon.
Once prey is detected, she'll first use Invisibility and remain hidden at distance, casting Displacement, Heroism and Haste before breathing down on her prey and then charging into melee to use wraithstrike+lots of natural attacks.
Should the enemy be using heavy use of magic, the Black Wyrm can use Anti Magic Field on herself (-1 to attack and damage rolls, -3 AC -8 to Fort and Reflex, -4 AC, -5 Will, plus losing other magic buff effects), then snatch away enemy spellcasters, carrying them away in her teeth to finish them off somewhere quieter and then returning to deal with his companions some other day.
Teleport allows for an escape route should things turn sour.
The Wyrm dragon has quite a bit of leftover wealth, it's up to you to invest it in specific scrolls or wands that she can activate with Use Magic Device.
Note the lavender and green iounstone and ring of Nine Lives as extra layers of protection.
