Gestalt Scarred Witch Doctor[PF]. Suggestions for other class levels?

[TC X0 Lt 0X]

I am currently building a Scarred Witch Doctor (PF Witch variant that cast from Constitution) for a Gestalt game centered around combating Fiends, and am having trouble deciding what levels to take for the opposite side of the Gestalt.

I was at first thinking Warlock, but I feel like the two won't synergize very well as I would have to choose between Eldritch Blast or Hexes each round in encounters, and would prefer my abilites complimenting each other.

I was thinking maybe Incarnum as well, but am not sure how effective it would be.

I am more or less out of ideas though. Any Suggestions?
Pretty much any 3.5 and PF is allowed, possibly including Dragon Mag. No 3rd Party.

You want something Con based for synergy, so Dragonfire Adept or an Incarnum class would be my first impulse.

Incarnum gestalts extremely well. Most of your abilities are static buffs so no problem using them at the same time as your witch abilities.

There's a couple of Soulmelds/ feats and such that directly tie Incarnum and casting together.

DFA is like Warlock but your Breath Weapon's save is Con based so it has more synergy. Entangling Exhalation+ DFA breath weapon is silly effective battlefield control for the amount of resources you spend on it. See if you're allowed to use metabreath feats on the DFA's weapon. Either just straight up or via the Dragonborn hack (be a dragonborn (a good call anyway. Con bonus and you're still an orc for witch doctor) and take the breath weapon so you qualify for the "recharge rate in rounds" clause of metabreath feats then use the feats to augment your DFA weapon.

I should have mentioned that I would have considered DFA, but I am currently playing one in another game.

So, uh, Incarnum then?

Incarnate is probably the best choice. It won't try to turn you into a gish and it has the most flexible and synergetic soulmeld list. It technically uses wis for saves but ignore that. There's like 3 melds with saves and they suck.

Totemist, on the other hand, will try to turn you into a gish but it also fits the Scarred Witch Doctor fluff perfectly and is somewhat more powerful than Incarnate, though somewhat less versatile.

Soulborn does not exist.

The Hex Strike feat allows you to channel your hexes through unarmed strike attacks, in case you'd like to multiclass with monk, unarmed fighter, or unarmed swordsage.

Warblade would give d12 HD and some decent saving throws, and you could take the save-boosting maneuvers and maneuvers such as Wall of Blades or Iron Heart Surge to boost your survivability without interfering with your Hex routines.

Hexblade (and the PHB II dark companion ACF) would boost your HD and would be very thematically appropriate. The Hex plus the Dark companion would give opponents -4 to their saves against your hexes. You could boost the saving throw penalties some more with Blackguard or Paladin of Tyranny, or some Binder vestiges.

Something else to consider would be Binder, which Gestalts quite well (or at least creates interesting combinations) and has Con as a possible primary ability score.

I did a one shot gestalting the class with Barbarian (just stick with out of combat / pre-combat buffs, cast before you rage, etc...) and using the con-based hair as my weapon.  Rage w/ Raging Vitality (and if 3E is in play you can probably jack con up higher) means very good con, also useful for slumber and misfortune DCs.  Only thing that didn't work out well was that I tried to go for a grapple build - PF grapple sucks unless you have it attached to your normal attacks for free like the Grab ability - and that was super-disappointing.

I decided to go with Nullblade, as seen Here.
