What the allowance actually buys
One allowance here buys 137,400 EXP, the best on the Lv 45 Blacksmith tradecraft rung — matched exactly by 1 other leve of the 6 there, with the rest trailing at 106,480 EXP or less.
Across that rung the return runs from 63,890 EXP to 137,400 EXP per allowance — 3 distinct figures spanning 115%, so the wrong pick leaves 73,510 EXP of the allowance unspent.
On whether to wait: the best Lv 50 Blacksmith tradecraft leve returns 456,810 EXP per allowance, 232% 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.
Cobalt Raising Hammer ×1 is a Lv 47 Blacksmith recipe, 3 steps deep through 4 intermediates, costing 15 units of raw material and 47 crystals.
Handing that in returns 9,160 EXP and 56 gil for every unit of raw material the order swallows, and the tree needs Armorer, Blacksmith and Carpenter.
