What the allowance actually buys
One allowance here buys 395,430 EXP, which places it 2nd of the 3 Lv 66 Alchemist tradecraft leves that record EXP. The best of them, Spell-rebound, returns 625,040 EXP for the same allowance, 58% more.
Across that rung the return runs from 237,260 EXP to 625,040 EXP per allowance — 3 distinct figures spanning 163%, so the wrong pick leaves 387,780 EXP of the allowance unspent.
On whether to wait: the best Lv 68 Alchemist tradecraft leve returns 681,530 EXP per allowance, 9% more than the best on this rung, while the Lv 64 rung behind tops out at 379,020 EXP.
At Lv 66 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 510,818 EXP per allowance, the 3 Fieldcraft ones 1,156,384 EXP, which puts this leve 23% below its own category's average.
Cunning Craftsman's Tea ×3 is a Lv 67 Alchemist recipe, a single step, costing 5 units of raw material and 9 crystals.
Handing that in returns 79,086 EXP and 324 gil for every unit of raw material the order swallows.
