IMO 15/3/2 SF/Monk/FVS. handwraps.
Haste boost and divine might from war soul tree
master of forms or grandmaster of forms for extra crit multi or dodge/saves
2 imbue dice from henshin cores
shintao tree for some goodies
ninja spy tree for dodge, subtlety and some extra sneak dice.
Run in t5 divine crusader, supplement with LD and shadowdancer.
depending on your racial ap, good options are drow, aasimar, tabaxi.. half elf.. human.
Right now i am playing a 14/6 sacred fist / dark apostate, just to meme, and it's actually decent, and fun.. mostly enhancements are self explanatory, haste boost from vistani, divine might from war priest. its no top end raid dps toon but it definitely does fine in questing. at level 29 with all level 15 gear I was doing decent damage in r3 IOD. it got a lot better with t5 divine crusader.
