If you're an alchemist, you either love the discovery system – or you despise it and wish to blast it back to the depths of Developers' Hell (that's one of those rock-and-lava zones, right?). Implemented with The Burning Crusade expansion, the discovery system gives alchemists a small (err, very small ... ok, very, very small ... ok, infinitesimally small) chance of discovering a new recipe every time they make a potion, elixir or flask. Players seem split between considering it a creative new mechanic or an annoying contrivance and roadblock, but after several patches and adjustments, the system seems here to stay.

Let's jump right in with your most burning question: Just how small (err, very small ... ok, very, very small ... ok, infinitesimally small) actually are your chances for making a discovery? Pretty darn small. Prior to patch 2.1, the most commonly cited figure floating around was 0.01%. (Discoveries were disabled via hot-fix for a short time just before patch 2.1, reportedly to prevent an exploit in which alchemists who repeatedly tried to create potions with no bag space could make discoveries without actually creating a potion or using potion ingredients.)

In patch 2.1, Blizzard noted that discovery rates were increased "significantly," but nobody seems to have performed (or published) an extensive enough analysis to pinpoint an honest number. One popular guesstimate puts the current discovery rate at 0.1% -- but really, your guess is as good as any. (Cauldron discovery rates are on a different table and run much higher than the general rate. Players report making cauldron discoveries, estimated at about 30%, as frequently as every one to five batches.)

Last night, Alchemists everywhere lost a wonderful ability. One which many (including my Druid) have not been able to savor the sweet success of. According to Tseric, there was a bug causing an exploitable situation in regard to potion/transmute discoveries. So, as was done with rogue poisons staying on when entering an instance, Blizzard has opted to temporarily remove the ability altogether for all alchemists to learn new potions, flasks and transmutes through discovery.

Per Tseric on the Profession forums:

We have been working on the resolution of a serious exploit in game which has led to certain consequences that we wanted everyone to be aware of. A hot fix has been recently applied to the alchemy profession, with regards to discoveries. For the time being, we have disabled all chance of a discovery, until we can implement the proper fix through a patch , as we can not resolve this matter solely with hot fixes. We apologize for the necessary but temporary removal of discoveries, and are working to have them re-implemented with an upcoming content patch.

While disheartening for the moment, at least it is only a temporary removal and not a permanent one. I'm sad to hear that my Druid will have to wait for some discoveries (she was so close, too!) but I'm certain Blizzard will get this remedied. It's just a question of if we'll see the alchemy discovery fix patch prior to, with, or after the 2.1 patch. That is, considering the focus on everything going on in the PTRs at the moment...
