The Long Lance of the Law

One allowance here buys 40,640 EXP, which places it 4th of the 6 Lv 30 Carpenter tradecraft leves that record EXP. The best of them, Live Freelance or Die, returns 67,730 EXP for the same allowance, 67% more.

Across that rung the return runs from 31,070 EXP to 67,730 EXP per allowance — 6 distinct figures spanning 118%, so the wrong pick leaves 36,660 EXP of the allowance unspent.

On whether to wait: the best Lv 35 Carpenter tradecraft leve returns 105,270 EXP per allowance, 55% 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 9% below its own category's average.

Gil ranks it differently: 184 gil per allowance is 5th of 6 on the same rung against 4th on EXP, with the best there paying 593 gil.

Steel Halberd ×1 is a Lv 29 Carpenter recipe, 2 steps deep through 4 intermediates, costing 11 units of raw material and 11 crystals.

Handing that in returns 3,695 EXP and 17 gil for every unit of raw material the order swallows, and the tree needs Blacksmith, Carpenter and Leatherworker.
