A Tree Grew in Gridania

One allowance here buys 105,270 EXP, the best of the 6 Lv 35 Carpenter tradecraft leves that record EXP: the runner-up manages 90,240 EXP, 14% less.

Across that rung the return runs from 25,910 EXP to 105,270 EXP per allowance — 6 distinct figures spanning 306%, so the wrong pick leaves 79,360 EXP of the allowance unspent.

On whether to wait: the best Lv 40 Carpenter tradecraft leve returns 102,600 EXP per allowance, 3% less than the best on this rung, while the Lv 30 rung behind tops out at 67,730 EXP.

At Lv 35 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 61,959 EXP per allowance, the 4 Fieldcraft ones 378,392 EXP, which puts this leve 70% above its own category's average.

Pastoral Oak Cane ×1 is a Lv 37 Carpenter recipe, 3 steps deep through 5 intermediates, costing 13 units of raw material and 17 crystals.

Handing that in returns 8,098 EXP and 46 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Carpenter, Goldsmith and Weaver.
