I mean, I don't think we should enchant the ithilmar armor if we get it -- I'd prefer to keep using the robes as our enchanted item in the slot and then replace them with some kind of fancier We-silk robe like we've been discussing lately. Runing the armor is I think right out, because even if any techniques of runing ithilmar have been preserved, I am not sanguine about it continuing to be Wind-magic-user-friendly with runes on it, and if we're enchanting something in the armor slot we might as well enchant our robes like we were planning to and just wear the armor in combination with it, such as in
this glorious concept art.
Like I said, I like this idea for reasons entirely orthogonal to "bigger numbers." The only number that goes up is our swag-o-meter.
