Leatherworker Leveling Guide
The 125 Leatherworker leves in this guide sit on 35 level rungs between Lv 1 and Lv 98, issued at 14 camps. Gridania is the fixed point — it issues on every rung up to Lv 45 while the second issuer rotates through the field camps — and from Lv 50 up each rung has exactly one.
The best EXP per allowance on a rung climbs from 1,160 at Lv 1 to 5,149,700 at Lv 98, but the climb is not steady: 6 rungs pay less than the rung below, the worst being Lv 80 at 935,000, down 42% on Lv 78.
Picking within a rung can matter more than which rung you are on: at Lv 40 the 6 leves on the board pay between 17,230 and 125,680 EXP for the same single allowance, a gap of 7.3×.
27 of the 125 carry a repeat count of 2, and they pay less per turn-in than the one-shot leve beside them on every one of the 21 rungs offering both. Counted as 3 turn-ins for a single allowance — the count is in the data, reading it as 3 deliveries is this site's assumption — the repeatable leve is still the better use of that allowance at 15 of those 21 rungs; take the one-shot at Lv 30, Lv 35, Lv 52, Lv 56, Lv 60, Lv 64.
Take the best leve on each of the 35 rungs and the Leatherworker ladder is worth 35,347,880 EXP for 35 allowances — 4th of the 8 crafting guides, 10% behind Weaver.
