Everybody Cut Footloose

One allowance here buys 90,590 EXP, which places it 3rd of the 6 Lv 40 Armorer tradecraft leves that record EXP. The best of them, Liquid Persuasion, returns 102,600 EXP for the same allowance, 13% more.

Across that rung the return runs from 61,560 EXP to 102,600 EXP per allowance — 4 distinct figures spanning 67%, so the wrong pick leaves 41,040 EXP of the allowance unspent.

On whether to wait: the best Lv 45 Armorer tradecraft leve returns 152,230 EXP per allowance, 48% more than the best on this rung, while the Lv 35 rung behind tops out at 82,760 EXP.

At Lv 40 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 72,545 EXP per allowance, the 4 Fieldcraft ones 560,212 EXP, which puts this leve 25% above its own category's average.

Gil ranks it differently: 756 gil per allowance is 2nd of 6 on the same rung against 3rd on EXP, with the best there paying 769 gil.

Mythril-plated Jackboots ×1 is a Lv 41 Armorer recipe, 3 steps deep through 3 intermediates, costing 12 units of raw material and 29 crystals.

Handing that in returns 7,549 EXP and 63 gil for every unit of raw material the order swallows, and the tree needs Armorer, Blacksmith and Leatherworker.
