Styg mentioned something to me that I didn't think of at first today, so I did some tests and discovered that his theory was correct: The extra procs on flasks you get from Elixir Master count towards the Mix Master guild achievement, which will allow us to make Battle Cauldrons for raids.

As such, if anyone in the guild, including Transmute and Potion Alchemists, has flasks to make, definitely send them to an Elixir Master in the guild such as myself - those Cauldrons are veeeerry cost efficient for raid flasks and we're already 1/3 of the way to the achievement.

Uvula is also an elixir master and will gladly mix your shit

Sapphyre is too! And finally maxed!

Athelas is an elixir master.
