I consistently wrap my head around what may be the best way to level up this sorcerer, but can't really stick to an idea without thinking "would there be a better way?"
Current build:
Words of Power Arcane Bloodline Sorcerer, Human, Neutral Chaotic
1: Metaword Mastery, Toughness
2, level 1 dip into Spellslinger: Nothing notable customizably
3: Point Blank Shot
4: Nothing notable
5: Precise Shot
6: Nothing notable
7: Improved Familiar
8: Improved Initiative (Bloodline feat)
9: Quickened Metamagic
10: New Arcana
11: Selective Spell Metamagic
12: Nothing notable
13: Dazing Spell Metamagic, New Arcana
14: Combat Casting (Bloodline feat)
15: Spell Perfection
The first question that is probably going to pop into peoples heads are "Why the level 1 dip into spellslinger?" A Spellslinger can cast any spell through his gun that are a ranged touch attack, cone, line, or ray, granting a bonus to the spells hit chance or increase the save DC by the enchantment bonus on the gun.
With the current iteration, you could in fact channel spells that belong to another class, such as sorcerer. With words of power, you can easily modify your spells in such a way that it could fit the descriptor for the gun, constantly taking advantage of the gun's bonus.
Next, Improved Familiar. It should be noted that the familiar that I have started out with is the scorpion, who gives +4 Initiative. The Improved Familiar that I will be going into is the Faerie Dragon, if I do decide that it is worthwhile.
The largest issues I am having is New Arcana and Spell Perfection. In long terms, I am hoping to gain permanency as the level 13 arcana, and at level 17 gain the spell Create Demiplane, for flavor purposes. This leaves the level 9 New Arcana, which would include level 4 and lower spells. Between the level 4 and lower spells, and the bloodline spells that I gain, those are the only available options to me in deciding what to give Spell Perfection to.
I have read some good recommendations (Dazing Ball Lightning, which is downright silly), although I was wondering if there were any other extremely effective choices given the small pool I have to work with, potentially with Quicken (The quicker I can get to blowing up the field the better).
Playstylewise, I am often going to be buffing myself at the start of battle to not be as squishy, followed by doing damaging spells that may also include debilitating effects (because words of power is awesome like that).
I'd suggest getting a elemental focus feat in there, and a spell focus as well. Sure, you'll be selecting the best save for the job once you level a bit, but a higher DC is always a good thing. And SF (Conj) is required for Augment Summoning - which you'll want once you start using the lovely standard action Servitor words.
