The Clamor for Hammers (L)

At 10 allowances a run, this leve's 534,960 EXP works out to 53,496 EXP per allowance, which places it 3rd of the 3 Lv 56 Blacksmith Grand Company leves that record EXP. The best of them, I'm a Lumberjack and I'm Okay (L), returns 402,314 EXP for the same allowance, 652% more.

Across that rung the return runs from 53,496 EXP to 402,314 EXP per allowance — 3 distinct figures spanning 652%, so the wrong pick leaves 348,818 EXP of the allowance unspent.

On whether to wait: the best Lv 58 Blacksmith Grand Company leve returns 446,249 EXP per allowance, 11% more than the best on this rung, while the Lv 54 rung behind tops out at 260,272 EXP.

At Lv 56 this data holds 54 leves paying EXP across 3 categories: the 27 Grand Company ones average 195,640 EXP per allowance, the 3 Fieldcraft ones 1,032,386 EXP and the 24 Tradecraft ones 390,755 EXP, which puts this leve 73% below its own category's average.

Titanium Lump Hammer ×1 is a Lv 57 Blacksmith recipe, 3 steps deep through 8 intermediates, costing 48 units of raw material and 51 crystals.

Handing that in returns 11,145 EXP and 28 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Blacksmith and Carpenter.

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 3,209,760 EXP and 7,956 gil for the 10 allowances it costs, or 320,976 EXP per allowance.
