Well I never specified my bloodline and I already have "Battle Sorcerer" in my CS. But I won't go dragonic. So I presume that my character has Arcane Bloodline by default? Maybe I could be elemental air-electrical bloodline. Just need to find the right page showing it's buffs for D&D 3.5 SRD.
Edit: I changed the attacking spell to "Lightning Ray" from "Lightning Bolt". I'll change it back if it bothers you.
