Not laying out two bucks to read up on Adaptive Hunter, but the two classic big ones are:
- Paladin 2 + Serenity feat to get Wis to all saves
- Shiba Protector 1 to add Wis to attack and damage rolls if you can deal with the feat tax
Also, since you are multiclassing around so much without moving anywhere, I would seriously consider
War Mind. Full BAB and a good bit of wis-based Psionics for a lateral side step in careers.
