Uh, did you mean to say base dex of 100 and base luk of 125?
Given that you can get 15+ dex from a Zhelm, 2+ dex from gold emerald earrings, and 10+ dex from shoes, you'll end up with around just the amount of dex you need to equip a varkit (assuming you're a luk dit), but that's only if you use a luk sauna and cape.
Don't put any more AP into dex.
