To Protect My City, I Must Wear a Mask (L)

At 10 allowances a run, this leve's 534,960 EXP works out to 53,496 EXP per allowance, which places it 3rd of the 3 Lv 56 Carpenter Grand Company leves that record EXP. The best of them, A Sky Pirate's Life for Me (L), returns 361,242 EXP for the same allowance, 575% more.

Across that rung the return runs from 53,496 EXP to 361,242 EXP per allowance — 3 distinct figures spanning 575%, so the wrong pick leaves 307,746 EXP of the allowance unspent.

On whether to wait: the best Lv 58 Carpenter Grand Company leve returns 266,415 EXP per allowance, 26% less than the best on this rung, while the Lv 54 rung behind tops out at 260,272 EXP.

At Lv 56 this data holds 54 leves paying EXP across 3 categories: the 27 Grand Company ones average 195,640 EXP per allowance, the 3 Fieldcraft ones 1,032,386 EXP and the 24 Tradecraft ones 390,755 EXP, which puts this leve 73% below its own category's average.

Hallowed Chestnut Mask of Aiming ×1 is a Lv 56 Carpenter recipe, 3 steps deep through 8 intermediates, costing 34 units of raw material and 45 crystals.

Handing that in returns 15,734 EXP and 37 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Carpenter and Goldsmith.

The record carries a repeats value of 5. This site reads that as 5 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 3,209,760 EXP and 7,488 gil for the 10 allowances it costs, or 320,976 EXP per allowance.
