Alchemist Leveling Guide
The 125 Alchemist leves in this guide sit on 35 level rungs between Lv 1 and Lv 98, issued at 14 camps. Ul'dah 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 2,040 at Lv 1 to 4,183,380 at Lv 98, but the climb is not steady: 5 rungs pay less than the rung below, the worst being Lv 64 at 379,020, down 36% on Lv 62.
Picking within a rung can matter more than which rung you are on: at Lv 40 the 6 leves on the board pay between 20,000 and 94,280 EXP for the same single allowance, a gap of 4.7×.
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 17 of those 21 rungs; take the one-shot at Lv 52, Lv 58, Lv 60, Lv 68.
Take the best leve on each of the 35 rungs and the Alchemist ladder is worth 37,575,040 EXP for 35 allowances — 3rd of the 8 crafting guides, 4% behind Weaver.
