What the allowance actually buys
One allowance here buys 536,700 EXP, which places it 2nd of the 6 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 42,771 EXP to 811,360 EXP per allowance — 6 distinct figures spanning 1797%, so the wrong pick leaves 768,589 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 2 categories: the 48 Tradecraft ones average 327,945 EXP per allowance, the 6 Fieldcraft ones 716,251 EXP, which puts this leve 64% 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.
