Gold Is So Last Year

One allowance here buys 137,400 EXP, the best of the 6 Lv 45 Goldsmith tradecraft leves that record EXP: the runner-up manages 106,480 EXP, 23% less.

Across that rung the return runs from 45,340 EXP to 137,400 EXP per allowance — 5 distinct figures spanning 203%, so the wrong pick leaves 92,060 EXP of the allowance unspent.

On whether to wait: the best Lv 50 Goldsmith tradecraft leve returns 334,080 EXP per allowance, 143% more than the best on this rung, while the Lv 40 rung behind tops out at 79,510 EXP.

At Lv 45 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 98,250 EXP per allowance, the 4 Fieldcraft ones 733,026 EXP, which puts this leve 40% above its own category's average.

Electrum Circlet (Amber) ×1 is a Lv 45 Goldsmith recipe, 2 steps deep through 2 intermediates, costing 13 units of raw material and 31 crystals.

Handing that in returns 10,569 EXP and 63 gil for every unit of raw material the order swallows.
