Draconic Breath (Su): At 1st level, you gain the Draconic Breath feat. As a dragonheart mage, you realize some additional benefits from taking this feat. As stated in the feat description on page 102, you can use a standard action to change arcane spell energy into a breath weapon that deals 2d6 points of damage per level of the spell that you expend. As you gain levels in this prestige class, however, the amount of damage you can deal increases.

At 6th level, your breath weapon deals 2d8 points of damage per level of the spell you give up.

At 10th level, your breath weapon deals 3d6 points of damage per level of the spell you give up.

Spellcasting: At each level except 1st and 6th, you gain new spells per day and an increase in caster level (and spells known, if applicable) as if you had also gained a level in a spellcasting class to which you belonged before adding the prestige class level. You do not, however, gain any other benefit a character of that class would have gained. If you had more than one spellcasting class before becoming a dragonheart mage, you must decide to which class to add each level for the purpose of determining spells per day, caster level, and spells known.

Draconic Feat: At 2nd, 4th, and 8th level, you gain a bonus draconic feat. Choose any draconic feat for which you meet the prerequisite, as given on page 99.
