Belle of the Brawl

One allowance here buys 320,970 EXP, which places it 3rd of the 3 Lv 56 Armorer tradecraft leves that record EXP. The best of them, A Halonic Masquerade, returns 534,960 EXP for the same allowance, 67% more.

Across that rung the return runs from 320,970 EXP to 534,960 EXP per allowance — 3 distinct figures spanning 67%, so the wrong pick leaves 213,990 EXP of the allowance unspent.

On whether to wait: the best Lv 58 Armorer tradecraft leve returns 811,360 EXP per allowance, 52% more than the best on this rung, while the Lv 54 rung behind tops out at 473,220 EXP.

At Lv 56 this data holds 54 leves paying EXP across 3 categories: the 24 Tradecraft ones average 390,755 EXP per allowance, the 3 Fieldcraft ones 1,032,386 EXP and the 27 Grand Company ones 195,640 EXP, which puts this leve 18% below its own category's average.

Titanium Vambraces of Fending ×1 is a Lv 56 Armorer recipe, 3 steps deep through 7 intermediates, costing 36 units of raw material and 40 crystals.

Handing that in returns 8,916 EXP and 10 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Armorer, Blacksmith, Goldsmith and Leatherworker.

The record carries a repeats value of 2. This site reads that as 2 further turn-ins on the same leve — an assumption, because the source data defines no meaning for the field — which would put the ceiling at 962,910 EXP and 1,083 gil for the 1 allowance it costs, or 962,910 EXP per allowance.
