What the allowance actually buys
One allowance here buys 709,140 EXP, the best of the 3 Lv 64 Armorer tradecraft leves that record EXP: the runner-up manages 599,100 EXP, 16% less.
Across that rung the return runs from 359,460 EXP to 709,140 EXP per allowance — 3 distinct figures spanning 97%, so the wrong pick leaves 349,680 EXP of the allowance unspent.
On whether to wait: the best Lv 66 Armorer tradecraft leve returns 969,450 EXP per allowance, 37% more than the best on this rung, while the Lv 62 rung behind tops out at 595,710 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 63% above its own category's average.
Doman Iron Greaves of Maiming ×1 is a Lv 64 Armorer recipe, 3 steps deep through 6 intermediates, costing 30 units of raw material and 30 crystals.
Handing that in returns 23,638 EXP and 100 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Armorer, Blacksmith, Goldsmith and Leatherworker.
