At Lv 10 this data holds 52 leves paying EXP across 2 categories: the 4 Fieldcraft ones average 43,676 EXP per allowance, the 48 Tradecraft ones 8,265 EXP, which puts this leve 25% above its own category's average.

Nothing on the turn-in list is craftable in this data: Moraby Flounder ×3 has no recipe here, so 3 units must come from gathering, a vendor or a drop.

Swiftperch, Western La Noscea issues 23 leves in this dataset, all of them Lv 10, across 5 disciplines, and 3 of them are turned in somewhere other than where they were taken.
