What the allowance actually buys
One allowance here buys 806,710 EXP, the best of the 3 Lv 68 Blacksmith tradecraft leves that record EXP: the runner-up manages 408,920 EXP, 49% less.
Across that rung the return runs from 210,850 EXP to 806,710 EXP per allowance — 3 distinct figures spanning 283%, so the wrong pick leaves 595,860 EXP of the allowance unspent.
On whether to wait: the best Lv 70 Blacksmith tradecraft leve returns 693,190 EXP per allowance, 14% less than the best on this rung, while the Lv 66 rung behind tops out at 625,040 EXP.
At Lv 68 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 550,185 EXP per allowance, the 3 Fieldcraft ones 1,189,544 EXP, which puts this leve 47% above its own category's average.
Molybdenum Ball-pein Hammer ×1 is a Lv 69 Blacksmith recipe, 3 steps deep through 6 intermediates, costing 41 units of raw material and 52 crystals.
Handing that in returns 19,676 EXP and 85 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Blacksmith and Leatherworker.
