Benefit

As a standard action, you can convert an arcane spell slot into a breath weapon. The breath weapon is a 30- foot cone (cold or fi re) or a 60-foot line (acid or electricity) that deals 2d6 points of damage per level of the spell slot you expended to create the effect. Any creature in the area can make a Refl ex save (DC 10 + level of the spell used + your Cha modifi er) for half damage. This is a supernatural ability.

Special

If the breath weapon of your draconic forebears does not deal acid, cold, electricity, or fi re damage, you choose from among the four energy types mentioned above.
