I thought about Taeon, but to make a Taeon Tights piece suitable for all those situations I would have to go with:
Snow: Acc/Att +20
Leaf: TA+2
Dusk: DEX+10
Basically highest possible augs in those categories. Which is not really something very cheap/easy to do, except the leaf slot. Could take you over 60 mils and still not reach the amounts you want. Not what I'd call a particularly inspiring perspective for a piece that, even with such augs, would barely grant an increase over the current one.
That "perfect" Taeon would grant me over Manibozho:
+16 Accuracy
-8 Attack
-2 DEX
+4 STR
+4 TA
So judging at the three roles I listed before.
It would be greatly better for role number 3, likely better for role number 2, not so sure on role number 1 (which is the main one). Probably slightly better? (less DEX, less Att, more TA)
I dunno, the randomness of Augments kinda demotivates me from even trying (already have Taeon Tights on mule of course).
But maybe that's just my bias because of bad experiences with past Random augmentation systems (spent like ~70 mils in stones, and I can't claim I have obtained anything particularly noteworthy, a couple of pieces maybe but no more)
