Paladin + Fighter + Monk...

[WangChi]

I've 12 paladin levels, 2 monk levels, 1 fighter levels.

I'm done leveling paladin - with that in mind, would it be better to go 6 fighter (kensei) / 2 monk or 6 monk (ninja spy) / 2 fighter?

Any advice would be appreciated. I was originally thinking DoS II/Kensei I, but now I'm torn and thinking of going DoS II/NS I.

Thanks.

Personally, at this point in your build, I'd go 14 Paladin (for Zeal) / 4 fighter (weapon Specialization) / 2 monk.

But if you really don't want any more paladin levels I think we'd need more info on your build and what you're after. TWF or THF, tank or "off tank"/DPS, group build or solo build.

6 fighter would give you 1 more feat, slightly more DPS, slightly higher BAB.
6 monk would give you a very impressive defensive ability in Shadow Fade, disease immunity, 10% heal amp, potentially second tier stances if you fight centered. (Somewhat counterintuitively, it will not give you any better saves.)

Another option is LR+1ing out of fighter and going 18 paladin / 2 monk.

Paladins already have disease immunity.
The 18/2 split is a solid build, but if you're not into LRing I'd still suggest taking 14 levels of paladin for the cheap DR breaking weapons it gives you (Holy Sword) and Zeal.
If you still really want only 12 pally levels, I'd suggest sticking to your plan with 6 fighter and 2 monk. 12 Paladin 8 Monk using unarmed would be better than 12 pally/6monk/2fighter. 8 monk will get you another die step on your unarmed damage and Healing Amp II.

I like the 12fighter/6pally/2monk split. rogue is also a nice splash for full UMD and hamgstring feat.

Agreed on 18 paladin/2 monk as the best option if you can LR.
