What the allowance actually buys
One allowance here buys 168,310 EXP, the best of the 6 Lv 45 Carpenter tradecraft leves that record EXP: the runner-up manages 111,430 EXP, 34% less.
Across that rung the return runs from 26,790 EXP to 168,310 EXP per allowance — 6 distinct figures spanning 528%, so the wrong pick leaves 141,520 EXP of the allowance unspent.
On whether to wait: the best Lv 50 Carpenter tradecraft leve returns 334,080 EXP per allowance, 98% more than the best on this rung, while the Lv 40 rung behind tops out at 102,600 EXP.
At Lv 45 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 98,250 EXP per allowance, the 4 Fieldcraft ones 733,026 EXP, which puts this leve 71% above its own category's average.
Gil ranks it differently: 845 gil per allowance is 2nd of 6 on the same rung against 1st on EXP, with the best there paying 1,145 gil.
Cobalt Trident ×1 is a Lv 47 Carpenter recipe, 2 steps deep through 3 intermediates, costing 14 units of raw material and 36 crystals.
Handing that in returns 12,022 EXP and 60 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Blacksmith and Carpenter.
