What the allowance actually buys
One allowance here buys 67,730 EXP, the best of the 6 Lv 30 Blacksmith tradecraft leves that record EXP: the runner-up manages 52,220 EXP, 23% less.
Across that rung the return runs from 31,330 EXP to 67,730 EXP per allowance — 4 distinct figures spanning 116%, so the wrong pick leaves 36,400 EXP of the allowance unspent.
On whether to wait: the best Lv 35 Blacksmith tradecraft leve returns 72,600 EXP per allowance, 7% more than the best on this rung, while the Lv 25 rung behind tops out at 47,200 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 51% above its own category's average.
Steel Falchion ×1 is a Lv 31 Blacksmith recipe, 2 steps deep through 3 intermediates, costing 11 units of raw material and 15 crystals.
Handing that in returns 6,157 EXP and 38 gil for every unit of raw material the order swallows, and the tree needs Blacksmith, Carpenter and Goldsmith.
