"Bonus Feats: At 3rd level and every 3 levels thereafter, a warpriest gains a bonus feat in addition to those gained from normal advancement. These bonus feats must be selected from those listed as combat feats. The warpriest must meet the prerequisites for these feats, but he treats his warpriest level as his base attack bonus for these feats (in addition to base attack bonuses gained from other classes and racial Hit Dice). Finally, for the purposes of these feats, the warpriest can select feats that have a minimum number of fighter levels as a prerequisite, treating his warpriest level as his fighter level."
1.) Was this supposed to be intended to only apply to the few bonus Feats they receive, or was it supposed to be all Feats?
2.) It indicates that "use BaB for these Feats" as opposed to the later treat warpriest levels as Fighter levels "for prereqs only". Do you get to retain that pseudo full BaB when using you Bonus Feats, or was that supposed to read more like "for meeting prereqs only, the warpriests act as if they had full BaB for their warpriest levels and also those warpriest levels as if they where Fighter levels but only for meeting prereqs of feats such as Weapon Specialization.
3.) If it only applies to Bonus Feats, then it's kind of pointless, as the Bonus Feats do not line up with the levels for such Feats, requiring you to retrain into them at later levels. Or to multiclass with Fighter, which is basically the exact thing the entire class was supposed to do for you.
"Weapon of the Chosen (Combat)
The influence of your deity guides your favored weapon.
Prerequisites: Weapon Focus with deity’s favored weapon, must worship and receive spells from a deity.
Benefit: As a swift action, you can call upon your deity to guide an attack you make with your deity’s favored weapon. On your next attack in that round with that weapon, your weapon counts as magical for the purpose of overcoming damage reduction or striking an incorporeal
creature. If your attack misses because of concealment, you can reroll your miss chance one time to see whether you actually hit."
"Improved Weapon of the Chosen (Combat)
You gain even greater favor when you use your deity’s favored weapon.
Prerequisites: Weapon Focus with your deity’s favored weapon, Weapon of the Chosen†.
Benefit: This feat acts as Weapon of the Chosen, except you gain the benefits on all attacks until the start of your next turn. Your attacks gain a single alignment component of your deity—either chaotic, evil, good, or lawful—for the purpose of overcoming damage reduction. If your deity is neutral with no other alignment components, your attacks instead overcome damage reduction as though your weapon were both cold
iron and silver.
"Greater Weapon of the Chosen (Combat)
Your deity guides your hand when you fight with her favored weapon.
Prerequisites: Improved Weapon of the Chosen†, Weapon Focus with deity’s favored weapon, Weapon of the Chosen†, worship and receive spells from a deity.
Benefit: When you use your deity’s favored weapon to attempt a single attack with the attack action, you roll two dice for your attack roll and take the higher result. You do not need to use your Weapon of the Chosen feat to gain this feat’s benefit."
1.) These Feats where specifically intended for the warpriest. Was it then intentional to specify that they only work with a deity's favored weapon when that class moved away from that idea long ago?
2.) Weapon of the Chosen requires a Swift action to activate, for a class that is already extremely strapped for swift and other action types. It's a pretty mediocre benefit for how many class features it makes you loose in order to use it.
3.) Greater Weapon of the Chosen requires you to A.) make a single attack, and B.) doing so while using the Attack Action, which is a specific form of Standard Action. As written, that precludes you from using this with other feats like Vital Strike, (which can not be combined with others that require a specific action type). This really makes this entire chain a pretty bad Trap Chain of Feats, and a really poor option for warpriests who it was designed specifically for.
Your deity protects you against deadly attacks.
Prerequisites: Cha 13, Knowledge (religion) 5 ranks, ability to cast 2nd-level divine spells; blessings†, domains, or mystery class feature.
Benefit: You gain a bonus equal to your Charisma modifier on all saving throws. If your Charisma modifier is already applied as a bonus on all saving throw (such as from the divine grace class feature), you instead gain a +1 bonus on all saving throws."
Probably the single more contested option in the book. Would it be possible to rewrite the prereqs to something like
Prerequisites: Cha 13, Knowledge (religion) 5 ranks, ability to prepair 2nd-level divine spells; blessings† or domains class feature.
It's actually a pretty nice new little toy for pretty much everyone except the Oracle (where it's pretty clearly broken as heck). For the Oracle who is so SAD and Cha focused, it's a no-brainer Feat choice that offers benefits that are better then all of the other Save boosting Feats (possibly combined). For pretty much every other Divine caster class though, they are MAD, generally very strapped for Feats, and not likely to have a Cha over 14 or 16, which means it may be a nice boost, but not a must have.
