No Risk, No Reward

One allowance here buys 30,820 EXP, which places it 4th of the 6 Lv 25 Leatherworker tradecraft leves that record EXP. The best of them, Campaign in the Membrane, returns 41,630 EXP for the same allowance, 35% more.

Across that rung the return runs from 18,490 EXP to 41,630 EXP per allowance — 6 distinct figures spanning 125%, so the wrong pick leaves 23,140 EXP of the allowance unspent.

On whether to wait: the best Lv 30 Leatherworker tradecraft leve returns 67,730 EXP per allowance, 63% more than the best on this rung, while the Lv 20 rung behind tops out at 24,710 EXP.

At Lv 25 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 31,772 EXP per allowance, the 4 Fieldcraft ones 204,269 EXP, which puts this leve 3% below its own category's average.

Gil ranks it differently: 336 gil per allowance is 2nd of 6 on the same rung against 4th on EXP, with the best there paying 562 gil.

Toadskin Cesti ×1 is a Lv 28 Leatherworker recipe, 2 steps deep through 2 intermediates, costing 6 units of raw material and 9 crystals.

Handing that in returns 5,137 EXP and 56 gil for every unit of raw material the order swallows, and the tree needs Blacksmith and Leatherworker.
