Alchemy had no specializations before, and receives three in BC. An alchemist can choose from the following:
●Master of Potions: Gives a chance to receive an additional potion when creating a high level potion.
●Master of Elixirs: Gives a chance to receive an additional elixir when creating a high level elixir. Note that Flasks fall under this effect.
●Master of Transmutation: Gives a chance to receive an higher quality gains when transmuting materials
Note that the alchemy specializations do not give you access to specializations specific recipes. The masteries have a chance to activate somewhere between 10-25%. You will get between one and four additional potions, elixirs or transmuted items. Although the higher the number, the lesser the chance of it happening.

●Flask of Relentless Assault: Increases Attack Power by 360 for 2 hours.

●Destruction Potion: +2% spell crit chance and 120 spell damage for 15 seconds.
●Haste Potion: Increases Haste rating by 400 for 15 seconds.
