What the allowance actually buys
One allowance here buys 185,340 EXP, which places it 3rd of the 3 Lv 64 Blacksmith tradecraft leves that record EXP. The best of them, Killer Cutlery, returns 489,060 EXP for the same allowance, 164% more.
Across that rung the return runs from 185,340 EXP to 489,060 EXP per allowance — 3 distinct figures spanning 164%, so the wrong pick leaves 303,720 EXP of the allowance unspent.
On whether to wait: the best Lv 66 Blacksmith tradecraft leve returns 625,040 EXP per allowance, 28% more than the best on this rung, while the Lv 62 rung behind tops out at 705,130 EXP.
At Lv 64 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 435,661 EXP per allowance, the 3 Fieldcraft ones 1,139,405 EXP, which puts this leve 57% below its own category's average.
Gil ranks it differently: 1,498 gil per allowance is 2nd of 3 on the same rung against 3rd on EXP, with the best there paying 2,995 gil.
Oroshigane Ingot ×1 is a Lv 64 Blacksmith recipe, a single step, costing 5 units of raw material and 4 crystals.
Handing that in returns 37,068 EXP and 300 gil for every unit of raw material the order swallows.
