Elixir Master

Elixir Mastery is a specialization of Alchemy. It allows an alchemist to sometimes create an additional elixir when brewing elixirs. Note that this effect also applies to the creation of Flasks, which are considered a variation on elixirs.

Obtaining the Elixir Master specialization
This specialization is directly obtained by completing the quest from Lorokeem  at the Shattrath City. You must be at least level 68 to be offered this quest.

An alchemist who has specialized in one of the other two specializations can switch to this one by talking to the quest giver of their current mastery and pay a 150g fee. The character then has to talk to the quest giver of the mastery desired and instantly get the new mastery. This is possible only after the character has completed the quest to gain one or another of the Mastery abilities.
