What the allowance actually buys
One allowance here buys 937,250 EXP, the best of the 3 Lv 74 Goldsmith tradecraft leves that record EXP: the runner-up manages 387,820 EXP, 59% less.
Across that rung the return runs from 244,970 EXP to 937,250 EXP per allowance — 3 distinct figures spanning 283%, so the wrong pick leaves 692,280 EXP of the allowance unspent.
On whether to wait: the best Lv 76 Goldsmith tradecraft leve returns 919,160 EXP per allowance, 2% less than the best on this rung, while the Lv 72 rung behind tops out at 826,240 EXP.
At Lv 74 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 514,135 EXP per allowance, the 3 Fieldcraft ones 1,574,264 EXP, which puts this leve 82% above its own category's average.
Bluespirit Rod ×1 is a Lv 74 Goldsmith recipe, 3 steps deep through 5 intermediates, costing 28 units of raw material and 53 crystals.
Handing that in returns 33,473 EXP and 155 gil for every unit of raw material the order swallows, and the tree needs Blacksmith and Goldsmith.
