The resists are 1 higher, and more spread out, of a gold circlet (which is naturally medable), but it would be more important with it to enhance after crafting (as the resists aren't all in one category like with leather items.
Working around the AoF:
18/3/6/20/3
5 pieces needed for 52/67/64/50/67
Assumes POF to 255.
Gold Circlet:
Craft exceptional (normal tool) where as little as possible of the resists are in fire and poison.
Imbue 100 Luck, Fire resist, energy resist (both to 20), MR 2 and LMC 6.
Then Enhance with gold (more than others, this one needs to be done with enhancing last, because of the extra property that gold adds).
this will result in x/21/y/z/20, where x=2, y=4 and z=2, plus the 17-20 of the exceptional/lore bonus scattered in x/y/z.
This would be, on average, 8/21/10/8/20
This would leave approximately
44/46/54/42/47
for the other 4 items ...
(having made my own non-luck uber mage suit around a Pendant, I know how hard it can be - don't bother with the lucky necklace).
Craft the remaining 4 pieces from regular leather. Try to have the pieces total (roughly - assumes 8/21/10/8/20 circlet - adjust the numbers below for any differences - there will be at least 1 resist to spare)
24/31/25/27/32
IF you can get at least one armor piece being minimum in fire, one minimum in poison, 1 minimum in energy, and 2 minimum in cold, you can maximize your properties you can apply (and reach all 70), but that might not be easy. However, you can shift this around a bit (46 fire resist will eliminate the need for a fire imbue, but means making 2 imbues to a different resist, whose resist will need to be 15 points lower).
After you POF them, Imbue with luck, then enhance them, they will be
44/31/25/27/32, which means you get all your physical without imbuing.
This leaves 75 resists to imbue, optimally in just 5 imbues. If you can't get the resists as I described, you'll probably have to settle with one or more being in the high 60s instead of 70.
There are 16 properties left to imbue at this point.
Imbue all 4 parts with LMC 6
(12 left)
Imbue all parts with MR2
(8 left)
Imbue 3 parts with LRC 20%
(5 left)
Imbue the resists
(0 left)
Alternatively, if you need 6 resist imbues, you can go to 3 imbues of LMC 8, but will need the special ingredient (which will make things more costly).
You can further tweak the suit with some of the footwear from the cleanup (2% in one of the resists), one of the event cloaks (Melissa's cloak has 5% Fire, the Shadow Cloak has Regens & LMC, and the Ranger's cloak has kinetic eater, minor SDI & LMC), and the 140 luck version of the Conjurer's Garb robe from the Gypsy event.
