Recently in the Wrath of the Lich King beta, Alchemists were given a Passive ability called Alchemical Blood. More recently it was renamed to Mixology. Mixology's tooltip states, "You receive an increased effect when you drink any elixir or flask you are able to make."
Not bad! I mean, it sounds not bad. It doesn't really say what that effect is. A few guildmates and I decided to do a little bit of testing to figure it out, though. Using a few high-end Burning Crusade elixirs and low-end Wrath elixirs, we came to the conclusion that the bonus is around 25%. I would say 25% on the dot, but we ran into some conflicting numbers. Nearly 30% in one case, a little under 25% in another. That was probably the result of talents altering the outcome.
With the same 25% applying to flasks, that would add another +20 Damage to the Caster DPS flasks. Flask of Pure Death, for example, would now supply +100 Shadow, Fire and Frost damage. Not a bad deal, really. 20 damage doesn't quite match up to an Enchanter's ring enchants, but I think Wrath's Crazy Alchemist Potions will make up for that. Wild Magic, anyone?
