I Don't Zinc It's a Coincidence

This dataset records no EXP, no gil and no turn-in item for this leve, nor for any of the other 3 Lv 5 Miner fieldcraft leves, so the whole rung is left unranked and out of the search index.

The closest Miner fieldcraft rung that does carry one is Lv 50, 45 levels above this page, where the best of 6 leves returns 834 gil per allowance.

Scorpion Crossing, Western Thanalan issues 38 leves in this dataset, Lv 1 through Lv 5, across 5 disciplines, and 6 of them are turned in somewhere other than where they were taken.
