Splinter in the Sewers

One allowance here buys 103,350 EXP, which places it 3rd of the 3 Lv 50 Carpenter tradecraft leves that record EXP. The best of them, So You Think You Can Lance?, returns 334,080 EXP for the same allowance, 223% more.

Across that rung the return runs from 103,350 EXP to 334,080 EXP per allowance — 3 distinct figures spanning 223%, so the wrong pick leaves 230,730 EXP of the allowance unspent.

On whether to wait: the best Lv 52 Carpenter tradecraft leve returns 423,990 EXP per allowance, 27% more than the best on this rung, while the Lv 45 rung behind tops out at 168,310 EXP.

At Lv 50 this data holds 54 leves paying EXP across 3 categories: the 24 Tradecraft ones average 238,216 EXP per allowance, the 3 Fieldcraft ones 834,862 EXP and the 27 Grand Company ones 132,961 EXP, which puts this leve 57% below its own category's average.

Gil ranks it differently: 624 gil per allowance is 2nd of 3 on the same rung against 3rd on EXP, with the best there paying 686 gil.

Cedar Lumber ×1 is a Lv 51 Carpenter recipe, a single step, costing 5 units of raw material and 3 crystals.
