Imagine The Perfect Nightlord

25 Dex Base (25)
67 Dex ZHelm (92)
23 Dex HT Pendant (115)
23 Dex Earrings (138)

~138 Dex should be enough to use an Osfa set. Red Osfa top would give another Dex point. Same goes for the Red Osfa pants adding another Dex point.

~Stats on the Dark Pirate Top and Bottom are off anyway. Perfect Gachable is 2 above average. You're missing 1 Luk on the Top and 1 Luk on the Bottom.

~Perfect Gachable (Purple) Sleeve is 57 Attack and 9 Luk. After Chaosing it should be 92 Attack/44 Luk

~Perfect Gold Emeralds are 4 Dex 7 Int, with a 30% Earring LUK and Chaos scrolls the final stats should be 24 Dex, 27 Int, 23 Luk

~Pink Gaia should be 30 Attack. 5 Attack is the highest base in all clients except for CMS, I believe.

So using the additives from correct equips, the stats at Level 120 should read:

94 STR
217 DEX
121 INT
831 LUK

211 Base Weapon Attack (w/ Crystal Ilbis)

But yeah, with Eye and Face Accessories, it'd be possible to achieve at least another 15 Dex. I'm not sure of which scrolls currently exist for them or if there are any new accessories that have Base AP.
