Sir, Dost Thou Even Heft

One allowance here buys 811,360 EXP, the best of the 3 Lv 58 Armorer tradecraft leves that record EXP: the runner-up manages 593,380 EXP, 27% less.

Across that rung the return runs from 94,450 EXP to 811,360 EXP per allowance — 3 distinct figures spanning 759%, so the wrong pick leaves 716,910 EXP of the allowance unspent.

On whether to wait: the best Lv 60 Armorer tradecraft leve returns 594,520 EXP per allowance, 27% less than the best on this rung, while the Lv 56 rung behind tops out at 534,960 EXP.

At Lv 58 this data holds 54 leves paying EXP across 3 categories: the 24 Tradecraft ones average 443,090 EXP per allowance, the 3 Fieldcraft ones 1,079,567 EXP and the 27 Grand Company ones 228,371 EXP, which puts this leve 83% above its own category's average.

Gil ranks it differently: 1,186 gil per allowance is 2nd of 3 on the same rung against 1st on EXP, with the best there paying 1,248 gil.

Adamantite Chain Hose of Fending ×1 is a Lv 59 Armorer recipe, 2 steps deep through 3 intermediates, costing 33 units of raw material and 39 crystals.

Handing that in returns 24,587 EXP and 36 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Armorer, Blacksmith and Leatherworker.
