Saw, Shank, and Redemption (L)

At 10 allowances a run, this leve's 331,500 EXP works out to 33,150 EXP per allowance, which places it 3rd of the 3 Lv 52 Blacksmith Grand Company leves that record EXP. The best of them, Too Big to Miss (L), returns 346,420 EXP for the same allowance, 945% more.

Across that rung the return runs from 33,150 EXP to 346,420 EXP per allowance — 3 distinct figures spanning 945%, so the wrong pick leaves 313,270 EXP of the allowance unspent.

On whether to wait: the best Lv 54 Blacksmith Grand Company leve returns 260,272 EXP per allowance, 25% less than the best on this rung, while the Lv 50 rung behind tops out at 251,250 EXP.

At Lv 52 this data holds 54 leves paying EXP across 3 categories: the 27 Grand Company ones average 177,755 EXP per allowance, the 3 Fieldcraft ones 868,208 EXP and the 24 Tradecraft ones 337,743 EXP, which puts this leve 81% below its own category's average.

Mythrite Culinary Knife ×1 is a Lv 53 Blacksmith recipe, 3 steps deep through 6 intermediates, costing 30 units of raw material and 33 crystals.

Handing that in returns 11,050 EXP and 34 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Blacksmith, Carpenter and Goldsmith.

The record carries a repeats value of 5. This site reads that as 5 further turn-ins on the same leve — an assumption, because the source data defines no meaning for the field — which would put the ceiling at 1,989,000 EXP and 6,084 gil for the 10 allowances it costs, or 198,900 EXP per allowance.
