What the allowance actually buys
One allowance here buys 49,940 EXP, which places it 4th of the 6 Lv 30 Armorer tradecraft leves that record EXP. The best of them, Aurochs Star, returns 67,730 EXP for the same allowance, 36% more.
Across that rung the return runs from 26,530 EXP to 67,730 EXP per allowance — 5 distinct figures spanning 155%, so the wrong pick leaves 41,200 EXP of the allowance unspent.
On whether to wait: the best Lv 35 Armorer tradecraft leve returns 82,760 EXP per allowance, 22% more than the best on this rung, while the Lv 25 rung behind tops out at 69,150 EXP.
At Lv 30 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 44,832 EXP per allowance, the 4 Fieldcraft ones 275,323 EXP, which puts this leve 11% above its own category's average.
Gil ranks it differently: 313 gil per allowance is 5th of 6 on the same rung against 4th on EXP, with the best there paying 520 gil.
Steel Sabatons ×1 is a Lv 30 Armorer recipe, 3 steps deep through 5 intermediates, costing 20 units of raw material and 28 crystals.
Handing that in returns 2,497 EXP and 16 gil for every unit of raw material the order swallows, and the tree needs Armorer, Blacksmith, Goldsmith and Leatherworker.
