So I've just gotten started with PFS play and it is extremely fun so far. I am playing a dual wielding cleric, not here to ask how viable it is (I know what it will be capable, I know a lot of things will be better than it and I'm okay with that. I'm a cleric, if I have to smack it in melee then I'm protecting the casters) but I am asking for advice on my 3rd level feat. The plan is to dip into fighter with the tactician archetype for skill points and bab and later on grab a few extra feats by furthering my fighter levels. Should I take the eclectic feat and grab an extra skill point, or should I grab the additional traits feat for reactionary (or similar trait) and magical knack to further my caster level?
Eclectic is sub-par. Even if you took half your levels in fighter rather than cleric, it's just +10 skill ranks or hit points. Take the toughness feat & get +20 hit points (by level 20, of course), instead. So I would very much recommend the Additional Traits if those are the two choices. Perhaps grab Protector of the Society instead of Reactionary, but as a partial cleric either is definitely fine. Caster level is worth keeping as high as possible.
Now for a comment you didn't ask for (sorry, can't help it!), I wanted to toss a reminder out that you do need a free hand to cast somatic spells. So careful when ya choose to dual wield. Tho a simple Weapon Cord could be an easy fix for that.
Oh I know I need a free hand, the off hand is on a weapon chord, and once I can pick up quick draw I can flick my wrist to around the world the offhand while casting. The final build is only 2 levels of fighter so I might just take additional traits for the +2 effective CL.
