Warpriest Weapon Focus

[WulFKrigan]

So a level 1 warpriest gets weapon focus. But the details on this are unclear.

A warpriest is a 3/4 BAB class, so they don't get +1 BAB. This means they get weapon focus despite the BAB requirements of the feat.

Does this mean that a warpriest can take a weapon they are not proficient in as well? If yes, does that provide proficiency?

By my read it sounds like you can take a non-proficient weapon and use it at -4 (lack of proficiency) +1 (weapon focus) = -3.

Is that accurate to RAW? Any PFS exceptions/FAQs to this?

You gain Weapon Focus as a Bonus Feat.

There is no general rule stating that you get to ignore the prerequisites of bonus feats.

Ergo, you still may only select a weapon that you're proficient in.

PFS has no special restrictions or rules regarding this.

Warpriests use their class level as Base Attack Bonus for determining prerequisites of Bonus Feats.

It's spelled out more clearly in their lv3+ Bonus Combat Feats section, but (I believe) there's been clarification that this also counts for Weapon Focus as a Bonus Feat at level one.

Accordingly, Warpriests also count their levels as Fighter levels when determining Bonus Combat Feats.

You must have proficiency in the weapon. A warpriest is already proficient in all simple + martial weapons and the deity favored weapon, so this usually inst a problem.
