What the allowance actually buys
One allowance here buys 536,700 EXP, which places it 2nd of the 3 Lv 58 Alchemist tradecraft leves that record EXP. The best of them, There Was a Late Fee, returns 811,360 EXP for the same allowance, 51% more.
Across that rung the return runs from 256,630 EXP to 811,360 EXP per allowance — 3 distinct figures spanning 216%, so the wrong pick leaves 554,730 EXP of the allowance unspent.
On whether to wait: the best Lv 60 Alchemist tradecraft leve returns 812,920 EXP per allowance, 0% more 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 21% above its own category's average.
Enchanted Aurum Regis Ink ×1 is a Lv 58 Alchemist recipe, a single step, costing 7 units of raw material and 5 crystals.
Handing that in returns 76,671 EXP and 160 gil for every unit of raw material the order swallows.
