Invoke the Draconic Blood [Reserve] (Draconium)

You call upon your blood sending it forth as a draconic 'creature'

Prerequisites: Dragonblood subtype, ability to cast a 4th level or higher spell which has a bonus if cast by a dragonblooded character or a sorcerer or is on the sorcerer spell list but not the wizard spell list.

Benefit: As long as you have a spell with a bonus if cast by a dragonblooded character or a sorcerer or which is on the sorcerer spell list but not the wizard spell list (heretofore referred to as a 'draconic spell') of 4th level or higher available to cast, you can summon a pseudodragon within a range of 30 feet. The pseudodragon acts as if summoned by a summon monster spell (PH 285) except you may select a color (Black, Blue, Green, Red, or White) for the pseudodragon. It gains a breath weapon usable every 1d4 rounds dealing 2d6 damage with a reflex save to half (DC 12, Con based) with a shape and energy type based upon the color chosen and immunity to the same energy type. Black is a 30 ft line of acid, Blue is a 30 ft line of lightning, Green is a 15 ft cone of acid, Red is a 15 ft cone of fire, and White is a 15 ft cone of cold. The duration of the summoning is equal to 1 round per level of the highest-level conjuration (summoning) spell you have available to cast.
You can have only one summoned dragon from this feat at a time; if you use the ability a second time, the first dragon disappears. Also, you must remain close to the dragon you summon. If at the end of your turn you are more than 30 feet from the dragon, it disappears.
If you have a conjuration (summoning) spell of 6th level or higher available to cast, you can summon a spiked felldrake instead. If you have a conjuration (summoning) spell of 8th level or higher available to cast, you can summon a wyvern instead. Like with the pseudodragon you select a color and they gain a breath weapon and energy immunity based upon that. Spiked felldrakes gain a 4d6 breath weapon with a 30 ft cone or 60 ft line (DC 15), wyverns gain an 8d6 breath weapon with the same length as a felldrake's and a DC of 15.

As a secondary benefit, you gain a +1 competence bonus to your caster level when casting 'draconic spells'.
