Draconic Sorcerer / Dragon Disciple + Eldritch Heritage Feat

[superspartan999]

So this is my first Pathfinder campaign, and the GM is letting us reroll our characters after the first chapter (up to level 6) since we have a better handle on the mechanics. I'm reclassing my human draconic sorcerer (lvl 6) as a draconic sorcerer (lvl 5) + dragon disciple (lvl 1).

I'm planning on using his bonus AC (Natural armor + mage armor + shield) and combat modifiers to allow him to get close and cast Burning Hands when there are lots of baddies. Otherwise, he'll probably play like a sorcerer against single baddies since Flaming Sphere is pretty awesome. His backstory is abandoned barbarian due to his draconic heritage, so he survived in the wild for years on his own and learned how to fight and all that stuff. So I figure he's a little savage, not afraid to rush into combat, but also not stupid enough to do so if he doesn't have to.
Anywho -

Str: 15
Dex: 16
Con: 16
Int: 16
Wis: 10
Cha: 18

(We rolled for stats, and I rolled REALLY well apparently haha)

Anyway, I've been having a really hard time figuring out what feats I want to pick. I get 3 + 1 (for human), and I've more or less settled on Combat Casting and Arcane Strike as those look extremely useful in general.

I'm debating on taking Toughness or Quicken Spell at the moment because those are class feats, so I kinda just want to wait to take one (probably toughness) at lvl 7. Maybe this is a bad idea?

Anyway to the main point of my question: I really like the idea of Eldritch Heritage as a feat, and I'm wondering if it's worth taking two feats (one for skill focus and one for heritage feat) to gain the first level powers of another bloodline. I'm looking at Arcane Bloodline (for a dragonling or reptile familiar), deep earth bloodline (for tremor), or verdant bloodline (for the snare vine).

My main question is is the double feat worth the extra power aside from the story element? If not, what feats would be good for this playstyle?

quicken spell takes a slot 4 levels higher. It is good, but you can't make use of it until level 10.

If you want to be in the thick of combat, which the use of combat casting and arcane strike suggest, then toughness could also be a good choice. Perhaps might want to include dodge as well. If using traits, highly consider magical knack to offset the casting level loss of Dragon Disciple.

If you were to get another bloodline, Abyssal actually suits you well. Extra uses of claws and with improved eldrich heritage you can get the strength bonus, which stacks with strength bonus of Dragon Disciple.

I actually really like that magical knack trait. It'll allow me to keep my level 3 spell and only cost me a feat which I can't find much that I want anyway...

If you really like Eldritch Heritage, as a Human you can take a variant race trait called Focused Study. This allows you to trade in your bonus Human feat for Skill Focus at level 1, and an additional Skill Focus at 8 and 16.

If you're considering Eldritch Heritage, consider Abyssal. Not for the first use of the Feat, but for the second. (The first use isn't bad since it gets you another pool of claws to draw from if you need them.) That grants a +2 Inherent Bonus to Strength (stacks with the Strength Bonuses granted by Dragon Disciple). Additionally, I believe that the bonus would go to +4 at character level 15.

Not a lot of Feats out there that will grant you +2 to +4 to you Strength as an Inherent Bonus.

Magical Knack trait just adds to caster level, not your equivalent sorceror level.

So, in this case, you'll still cast spells with CL 6, but you'll be limited to the spell slots and spells known etc of sorceror 5. You won't have those tasty 3rd level spells until 7th level.

Combat reflexes and a reach weapon wouldn't be bad. You can hold the weapon in one hand as a free action while casting, then back to 2hand wielding as another free action.

2 handing can still be a problem if you want to use metamagic rods instead. Gloves of Storing can help with that. If you take Craft Rod you can make your own quicken and other (dazing!) rods eventually.

If you like your burning hands, intensify metamagic can keep it growing with you for a while longer. Spell focus and spell specialization can also help with that, and you can shift that bonus to better spells as you level up.

If possible, swap the INT and the STR. As Dragon Disciple, you'll be a switch-caster, more akin to a Cleric than a regular Wizard. INT is nice to have, but if you want to dive into melee, STR is more important than INT.
