For the most usable dex:

Black/Red Pirate Bottom -> 3 luk 1 dex clean
Red Osfa Suit -> 5 luk 2 dex clean

1x High grade Dex Crystal = +5 dex
1x High grade Dark Crystal = -5 to +5 dex/luk

Perfect outcome:
Black/Red Pirate Bottom: 8 luk 11 dex
Red Osfa Suit: 10 luk 12 dex

Given the Osfa only requires 30 less dex than the Reverse weapons, you have to go for the Pirate bottom if you want to scroll it. +9 70% = 8 luk 29 dex. If you drop to level 70 bottom you only get 1 crystal slot, and the best outcome you can do is a 25 dex pants.

This outfit adds 18 luk, 41 dex, plus whatever other luk you put on the top (ideally, 36 luk 41 dex?). From 120 dex req. of the pants, that's 161 total. If you switch to the dex-based GreenPirate/BrownOsfa, you get an extra 5 dex to work with, meaning less emphasis on "perfect" dark crystals.


Overall is more limited, as they all require the same dex as the claws - if you use a level 100 overall, you get 2 crystal slots and can make it 17 dex 8 luk clean, w/ same dark/dex crystal pattern. Then luk-scroll it for perfect +12 60% outcome around 19 dex 30 luk, since you can only use 20 from the 140 req to get 160.
