So you want a solo/party build? Offense/support focused one? If you don’t like PD then Kabbalist is probably your choice.
There is a bunch of options you can get at Rank 6, such as:
Priest C1 for monstrance+blessing, if you have DEX builds in your party. Resurrection is also good to have for occasional uses.
Bokor C1 for Hexing and Effigy, as well as extra meatwall (especially sturdy with full SPR builds).
Dievdirby C1 for CDR, SP recovery(though you won’t need it too much with Kabbalist) and group warp.
Paladin C1 for HP Regen synergy with Aukuras (especially good if you max it instead of Zaibas - in full support builds), extra DPS on Mutant/Devil Type mobs and useful Resistances buff.
Oracle C1 for it’s great utility and magic immunity from counter spell.
Less effective but still viable options:
Druid C2 is also a decent idea, but I personally don’t like this class.
Priest C2 for revive and mass heal. Or swap ClericC2 for Priest C3 to get Stone Skin.
Paladin C2 for Conversion. Or swap ClericC2 for Paladin C3 to get Barrier.
Dievdirby C3 for Ausrine, Owl and World Tree. (C2 is quite bad).
Or even Bokor C3 with full INT if you are into such things)
