The Garden of Arcane Delights (L)

At 10 allowances a run, this leve's 428,020 EXP works out to 42,802 EXP per allowance, which places it 3rd of the 3 Lv 54 Alchemist Grand Company leves that record EXP. The best of them, It's Gonna Grow Back (L), returns 485,295 EXP for the same allowance, 1,034% more.

Across that rung the return runs from 42,802 EXP to 485,295 EXP per allowance — 3 distinct figures spanning 1,034%, so the wrong pick leaves 442,493 EXP of the allowance unspent.

On whether to wait: the best Lv 56 Alchemist Grand Company leve returns 294,229 EXP per allowance, 39% less than the best on this rung, while the Lv 52 rung behind tops out at 264,372 EXP.

At Lv 54 this data holds 54 leves paying EXP across 3 categories: the 27 Grand Company ones average 205,186 EXP per allowance, the 3 Fieldcraft ones 938,680 EXP and the 24 Tradecraft ones 400,590 EXP, which puts this leve 79% below its own category's average.

Enchanted Hardsilver Ink ×1 is a Lv 54 Alchemist recipe, a single step, costing 7 units of raw material and 4 crystals.

Handing that in returns 61,146 EXP and 156 gil for every unit of raw material the order swallows.

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 2,568,120 EXP and 6,552 gil for the 10 allowances it costs, or 256,812 EXP per allowance.
