Fire for Hire

One allowance here buys 408,920 EXP, which places it 2nd of the 3 Lv 68 Blacksmith tradecraft leves that record EXP. The best of them, Hammer and Sails, returns 806,710 EXP for the same allowance, 97% more.

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 26% below its own category's average.

Gil ranks it differently: 1,262 gil per allowance is 3rd of 3 on the same rung against 2nd on EXP, with the best there paying 3,494 gil.

Molybdenum Rimfire ×1 is a Lv 68 Blacksmith recipe, 3 steps deep through 5 intermediates, costing 30 units of raw material and 38 crystals.

Handing that in returns 13,631 EXP and 42 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Blacksmith, Carpenter and Leatherworker.
