Riches' Brew

One allowance here buys 41,410 EXP, the best on the Lv 30 Alchemist tradecraft rung — matched exactly by 3 other leves of the 6 there, with the rest trailing at 27,950 EXP or less.

Across that rung the return runs from 21,740 EXP to 41,410 EXP per allowance — 3 distinct figures spanning 90%, so the wrong pick leaves 19,670 EXP of the allowance unspent.

On whether to wait: the best Lv 35 Alchemist tradecraft leve returns 72,600 EXP per allowance, 75% more than the best on this rung, while the Lv 25 rung behind tops out at 43,600 EXP.

At Lv 30 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 44,832 EXP per allowance, the 4 Fieldcraft ones 275,323 EXP, which puts this leve 8% below its own category's average.

Gil ranks it differently: 296 gil per allowance is 3rd of 6 on the same rung against 1st on EXP, with the best there paying 440 gil.

Hi-Potion of Mind ×3 is a Lv 31 Alchemist recipe, a single step, costing 3 units of raw material and 6 crystals.

Handing that in returns 13,803 EXP and 99 gil for every unit of raw material the order swallows.
