My rogue is wearing chain hauberk, and I want to get her MnE spell hindrance down to the minimum, which is 12%. According to the chart, I need 130 ranks of armor use to attain this.
Right now, I have 110 ranks, and have a hindrance of 24%. She isn't likely to get that before cap (she's level 96.5 now). Approximately how much will the spell hindrance drop per rank of additional skill at this point?

I want the data because I also have to factor in what other skills I want to emphasize, and divvy up her current accumulated TPs appropriately.

If you've got two different Fusion pieces, I note that there is both a +11 bonus and a +10 bonus orb on PlayerShops right now, so two million coins will get you there in a moment.
If you use 1HEdged, there's a scimitar--sure, it's a crappy weapon type, but at your level there's a good chance you're using aimed shots, anyhow--that is also +10 bonus, so you could do it with only a single Fusion item.

Armor enhancives are really rare. If they weren't, I would have bought a bunch and gone for 330 armor ranks, just to see if I could tell the difference. But they're very rare at the high end, and there are other priorities.

+50 yes, 202 would depend on profession.

Yeah, I forgot about the triple-train. <duck> It's been a while since I played any of my Warriors.
