Heavy Hitter

One allowance here buys 826,240 EXP, which places it 2nd of the 3 Lv 72 Blacksmith tradecraft leves that record EXP. The best of them, Selective Logging, returns 954,450 EXP for the same allowance, 16% more.

Across that rung the return runs from 418,810 EXP to 954,450 EXP per allowance — 3 distinct figures spanning 128%, so the wrong pick leaves 535,640 EXP of the allowance unspent.

On whether to wait: the best Lv 74 Blacksmith tradecraft leve returns 646,380 EXP per allowance, 32% less than the best on this rung, while the Lv 70 rung behind tops out at 693,190 EXP.

At Lv 72 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 590,811 EXP per allowance, the 3 Fieldcraft ones 1,405,338 EXP, which puts this leve 40% above its own category's average.

Gil ranks it differently: 4,090 gil per allowance is 1st of 3 on the same rung against 2nd on EXP, with the best there paying 4,090 gil.

Deepgold Knuckles ×1 is a Lv 73 Blacksmith recipe, 2 steps deep through 4 intermediates, costing 28 units of raw material and 45 crystals.

Handing that in returns 29,509 EXP and 146 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Blacksmith and Goldsmith.
