1) The available templates are:
Avian, Bramble, Cave, Clockwork, Crystal, Drowblood, Dunesage, Dust, Element-Infused, Force, Inveigler, Metal-Clad (Tin, Copper, Brass, Lead, Gold), Mist, Muck, Plantblood, Poisonous, Prismatic, Saurian, Scalding, Smoke, Time Seer, Unholy
Unholy was the only one that really seemed to suit this character, and didn't really have any physical change associated with it. There are some others I considered (Mist, for instance) but Strix have a natural flyspeed anyway. (Though Cloudsight would be hilarious for a mage or archer)
I'd PREFER to keep my base type as Humanoid so I can become a vampire. I don't think elementals (Mist) can go vampire
2) Sad that I can't have conductive arrows. I can still likely run a switch-hitter Antipaladin, though. Focus on a bow but carry a conductive weapon for when i'm forced into melee. Would taking a four level dip in Fighter hurt my performance as an Antipaladin terribly? Three levels was my original plan for three feats and Armor Training, but four gives me Weapon Specialization and allows access to Point Blank Master.
My plan was to take the first level of Fighter at Third, right after getting Cha-to-Saves, so I can nab Precise/Rapid or Precise/Hover or something. Second fighter level at 6 for Snap Shot and something else (that I forgot exactly) and third level around 11th so I can get Improved Precise and something else. I'll likely nab Power Attack and Flyby attack at some point too, in case I need to smash things, as I won't be able to fire in melee without four levels in FIghter.
Alternately I can go Ranger, which means I have to give up my Unholy template, but get favoured enemy to stack on top of Hatred, and early-access archery feats.
The other option was Wizard or Witch. Looking at either pure Wiz (Evocation/Admixture with Dazing Fireballs) and an Imp familliar, or Wizard/Diabolist with the same setup plus more demons and dual-wielding imps.
Witch would be a heavy debuff build my GM used before and had a blast with, still imp familliar (because it's fitting and come on, wand monkey) and maybe Diabolist anyway, but that would hurt my hex progression.
So, ah, yeah.
TLDR:
Archer Antipaladin sounds fun but I wonder if some fighter levels would hurt or help my build. (Or maybe go Warpriest?)
Alternately, Ranger, though what template?
Witch or Wizard, Diabolist or not? (Other casters are evil cleric and mesmerist, as a reminder)
If witch/wizard, stay unholy or go another template like Imveigler or somesuch?
And, ah, sorry for so many questions and such. I'm not TRYING to minmax, but I'm also horridly indecisive.
