I would go draconic bloodline myself.
What draws you to the draconic bloodline? I like this:
1. I could gain perception skill, which is cool. I guess? A lot of people say its great but I haven't done pathfinder enough to know how good it is.
2. But the bonus spells they get seem redundant to me. Maybe I could use my level ups to replace the previous dragon form spells that I won't be using? If my GM won't let me that makes me sad.
3. Natural Armor bonus seems cool. Squishy caster can always use more armor.
4. Wings! I love wings. Sounds so cool. Free fly spell basically right, without having to use spells per day?
5. Dragon Immunity at capstone is bloody awesome!
6. Finally the two parts that I hate. Level 1 = claw. Level 9 = Dragon breath. I don't care about these two at all. Since I don't care about these, would Tattooed Sorcerer powers be good for replacing these two? a. I can replace the claws, which I would never use, for a familiar that I can wear on my body whenever I want it to as ITS move action

. b. I can replace the breath attack, which I don't think much of, and in the process I can take one of the spells I know and make it a spell-like ability. I could officially take Time Stop as a tattoo spell-like ability later. How cool is that? I know that I can only use the tattoo spell once a day and the dragon breath up to three times a day, but I just feel like my ?d6 breath attack would end up looking a lot more like a ?d6/2
