An alchemy mastery is a one-time trainer quest that permanently procs extra output on one craft category. The gate is level 68 and 325 Alchemy. First pick is $18.44; moving off a mastery you already hold is $27.44.
Three masteries, three different Outland trainers, one quest each:
- Elixir Master — Lorokeem, Lower City in Shattrath. Master of Elixirs wants 10 Essence of Infinity off Rift Lords and Rift Keepers in The Black Morass, plus 5 Elixir of Major Defense, 5 Elixir of Mastery and 5 Elixir of Major Agility;
- Potion Master — Lauranna Thar'well, Cenarion Refuge in Zangarmarsh. Master of Potions wants the Botanist's Field Guide from the second boss in The Botanica, plus 5 Super Healing, 5 Super Mana and 5 Major Dreamless Sleep Potions;
- Transmutation Master — Zarevhi, The Stormspire in Netherstorm. Master of Transmutation wants 4 Primal Might — 20 primals once you count the Earth, Water, Air, Fire and Mana that feed them.
What the mastery actually pays: every craft in your own category rolls a chance to make 1 to 4 extra items at no extra material cost. There are no mastery-only recipes in TBC alchemy — the proc is the entire reward. A character holds exactly one mastery at a time, so a switch means 150 gold to unlearn at your current trainer and then running the new trainer's quest from scratch.
Which one is worth which player: Transmutation for gold, because Primal Might and gem transmute procs sell straight off the auction house; Elixir if you are the one bankrolling a raid's flask supply; Potion if your 25-man burns healing and mana pots by the stack and you want that volume back.
325 skill is the hard prerequisite. If your alchemist is short of it, the Alchemy Leveling 1-375 service on timesaver.gg takes the bar up first and this order picks up from there. Turnaround is 24-48 hours on US realms, booked around your own ET or PT play window. EU realms sit on the region switch above.
