You Burnt It, You Bought It

One allowance here buys 18,290 EXP, which places it 2nd of the 6 Lv 20 Goldsmith tradecraft leves that record EXP. The best of them, Music to Their Ears, returns 21,600 EXP for the same allowance, 18% more.

Across that rung the return runs from 8,990 EXP to 21,600 EXP per allowance — 5 distinct figures spanning 140%, so the wrong pick leaves 12,610 EXP of the allowance unspent.

On whether to wait: the best Lv 25 Goldsmith tradecraft leve returns 36,390 EXP per allowance, 68% more than the best on this rung, while the Lv 15 rung behind tops out at 24,790 EXP.

At Lv 20 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 17,352 EXP per allowance, the 4 Fieldcraft ones 113,304 EXP, which puts this leve 5% above its own category's average.

Gil ranks it differently: 192 gil per allowance is 4th of 6 on the same rung against 2nd on EXP, with the best there paying 292 gil.

Wind Brand ×1 is a Lv 23 Goldsmith recipe, 2 steps deep through 2 intermediates, costing 4 units of raw material and 6 crystals.

Handing that in returns 4,573 EXP and 48 gil for every unit of raw material the order swallows, and the tree needs Goldsmith and Leatherworker.
