What did the code slip from FFXIII to get the Asuran Armguards look like?

[Mjollnir]

I'll have to see what other gear has, but they could be useful for DoL for a while.

Not much so. The item is equippable at level 1 (yay!) and it lists the Item Level as 11, so it's overpowered for a level 1 item, but the first Hands slot item which also has +15 Gathering is unsurprisingly the level 11 Hard Leather Wristguards.

So you'll either replace them at lv11 with Hard Leather Wristguards +1 (idk stats on those tho), or lv16 with Goatskin Wristguards (+18 Gathering and two Materia slots).
