Transmute

Transmutation is a sub-skill of Alchemy. It is highly valued since it allows the transmutation of some metals, gems or elemental items into more valuable ones. Some items in-game are only obtainable through transmutation.

Requirements
All transmutations require the alchemist to have a Philosopher's Stone or any of the variants of the Alchemist Stone equipped or in their inventory.

Most transmutations are on a shared cooldown. The length of the cooldown varies by recipe, but prevents all transmutations until it has expired (including those which would initiate a shorter cooldown). Of note, however, the following transmutations do not have a cooldown:
 * Transmute: Arcanite
 * Transmute: Elemental Fire
 * Transmute: Primal Might
 * Transmute: Titanium
 * Transmute: Trillium Bar
 * Uncommon-to-rare gem transmutes, including Meta Gem transmutes.

Transmutation Master
"Allows an Alchemist to sometimes get greater results when transmuting materials" - When specialized as a Transmutation Master, there is a random chance that you create more than one item when transmuting. It's possible to get up to 5 items in a single process.

It has been reported that, when averaged, Transmutation mastery grants an increase in resulting items of about 20%. Given that a single transmute can result in up to 5 items, long stretches of "no additional results" may result.

Becoming a transmutation master prevents you from being a Potion Master or Elixir Master, however you can switch at any time by speaking with the Alchemy trainer in Orgrimmar or Stormwind:


 * Horde: Yelmak in Orgrimmar
 * Alliance: Lilyssia Nightbreeze in Stormwind
