Swords for Plowshares

One allowance here buys 617,600 EXP, which places it 2nd of the 6 Lv 58 Blacksmith tradecraft leves that record EXP. The best of them, Winter Weather Conditions, returns 811,360 EXP for the same allowance, 31% more.

Across that rung the return runs from 102,934 EXP to 811,360 EXP per allowance — 6 distinct figures spanning 688%, so the wrong pick leaves 708,426 EXP of the allowance unspent.

On whether to wait: the best Lv 60 Blacksmith tradecraft leve returns 703,720 EXP per allowance, 13% less than the best on this rung, while the Lv 56 rung behind tops out at 731,480 EXP.

At Lv 58 this data holds 54 leves paying EXP across 2 categories: the 48 Tradecraft ones average 327,945 EXP per allowance, the 6 Fieldcraft ones 716,251 EXP, which puts this leve 88% above its own category's average.

Gil ranks it differently: 406 gil per allowance is 5th of 6 on the same rung against 2nd on EXP, with the best there paying 1,248 gil.

Adamantite Zweihander ×1 is a Lv 58 Blacksmith recipe, 2 steps deep through 5 intermediates, costing 52 units of raw material and 54 crystals.

Handing that in returns 11,877 EXP and 8 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Blacksmith, Carpenter, Goldsmith and Leatherworker.
