One for the Books

One allowance here buys 2,040 EXP, the best of the 6 Lv 1 Alchemist tradecraft leves that record EXP: the runner-up manages 1,330 EXP, 35% less.

Across that rung the return runs from 800 EXP to 2,040 EXP per allowance — 4 distinct figures spanning 155%, so the wrong pick leaves 1,240 EXP of the allowance unspent.

Lv 1 is the lowest rung this data records for Alchemist tradecraft leves, and the next one, Lv 5, tops out at 6,280 EXP per allowance — 208% more than the best available here.

At Lv 1 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 1,110 EXP per allowance, the 4 Fieldcraft ones 19,656 EXP, which puts this leve 84% above its own category's average.

Gil ranks it differently: 114 gil per allowance is 2nd of 6 on the same rung against 1st on EXP, with the best there paying 115 gil.

Leather Grimoire ×1 is a Lv 5 Alchemist recipe, 2 steps deep through 3 intermediates, costing 7 units of raw material and 5 crystals.

Handing that in returns 291 EXP and 16 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Leatherworker and Weaver.
