What the allowance actually buys
One allowance here buys 14,920 EXP, which places it 5th of the 6 Lv 15 Alchemist tradecraft leves that record EXP. The best of them, Book and a Hard Place, returns 22,790 EXP for the same allowance, 53% more.
Across that rung the return runs from 11,040 EXP to 22,790 EXP per allowance — 4 distinct figures spanning 106%, so the wrong pick leaves 11,750 EXP of the allowance unspent.
On whether to wait: the best Lv 20 Alchemist tradecraft leve returns 21,600 EXP per allowance, 5% less than the best on this rung, while the Lv 10 rung behind tops out at 12,030 EXP.
At Lv 15 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 16,554 EXP per allowance, the 4 Fieldcraft ones 78,432 EXP, which puts this leve 10% below its own category's average.
Potion of Vitality ×3 is a Lv 18 Alchemist recipe, a single step, costing 3 units of raw material and 2 crystals.
Handing that in returns 4,973 EXP and 57 gil for every unit of raw material the order swallows.
