So looking at the monk it has Hit Dice 0 (D4) and Fighting value 1b. This would have an XP cost of 500 leaving an XP of 1700 unaccounted for. Additionally, to get down to the extremely restricted weapon choices we'd have 4 custom powers (two to go from broad to broad to narrow, one to go from narrow to restricted and one to eliminate one fighting style), and perhaps another custom power since we are ditching 3 possible weapons and allowing only daggers. So the Mystic would have 5 custom powers.
Maybe Defense and Attack modes cost 1/2 a custom power for classes with a psionic value? in which case the custom powers would cover the psionic attack defense modes, then we would assume a psionc value of 4 cost 1700 xp? does that seem fair?
If we assume a descending progression of PSPs then if 5 is at value four then the monk would be at value 1 with 2 psp per level, and only one Chakra until level 7. Maybe the ability to gain additional chakras at higher level is a custom Power?
