Help with exactly half of the battle. [PFS]

[Jayson MF Kip]

One of my PFS characters just finished Way of the Kirin and

Way of the Kirin spoiler:

now needs to choose a new faction. As such, it seemed appropriate to have some sort of "new beginning."

The character:

(Just reached level 6 feats/skills not yet taken.)

Halfling Rogue (Filcher)

10 STR
20 DEX
12 CON
14 INT
12 WIS
10 CHA

1-Imp. Unarmed
2-(talent)Weapon Finesse
3-Sap Adept
4-(talent)(ninja trick)Deflect Arrows
5-Sap Master

Way of the Kirin spoiler:

I also have one Ability score increase to apply from Way of the Kirin.

I'm going to use the Level 6 talent to get Kirin Style via ninja trick.
As such, I will need to spend 6 ranks on Knowledge (Arcana). I already have 5 ranks in Knowledge (Local). That leaves me with 5 available skill ranks for this level. As such, I'm wondering how best to allocate said ranks towards knowledge skills to get the most out of Kirin Style.

Also, is there any easy way (besides multiclassing) to get more knowledge skills as class skills? (I'm not beyond paying prestige).

Take two levels of lore warden fighter for all Knowledges and two bonus feats, on top of free Combat Expertise.

You will only lose 4 skill ranks per level, which is worth it for all Knowledges as class skills.

[Jayson MF Kip]

Anything without multiclassing?

And which knowledge skills should be a priority (besides arcana for the feat chain)?

[Mergy]

There's the Cosmopolitan feat, or the Extra Traits feat.

A certain season 4 adventure gives a possibility of getting Knowledge (Arcana) as a class skill, but it might cost you an atonement.

Losing a few rogue levels for a few fighter levels and all Knowledges is a pretty good trade though. You could grab Kirin Style now, and then save your second fighter level for 12 when you qualify for Kirin Path.

Alternatively, don't worry about class skills so much. It's only a +3, and that's not a big deal once you get higher in level.

That is half the battle.
