I’m currently opting for 2 builds with Krivis-Taoist, one autoattacker with Krivis3>Paladin3>Taoist and one caster with Krivis3>Bokor3>Taoist.
The Paladin build would be CON/DEX rest INT (basically 200 DEX,150 CON, rest INT), the Bokor INT/SPR rest CON (basically 200 SPR, 170 INT, rest CON).
Builds are Paladin

and Bokor

gotta see how well those two fare, but I doubt that any of them would perform badly at Rank 9.
