Jagoex sent a followup on the speculation around the Mad Alchemist's Potion that us Alchemists are getting in the next patch. We've already seen a few buffs come in, but Jagoex found a few more: Adept's Elixir, Earthen Elixir, and Elixir of Mastery and Major Fortitude all popped up from the potion proccing. It's pretty wild how random these buffs will get, and unfortunately, that makes them fairly useless-- there's no way a strength buff would help casters. However, as cheap as these are (we're told that it only takes a few Ragveil to make them-- AH speculators take heed), it might be worth it to make a bunch, and then just keep canceling buffs and drinking until the right buff is achieved.
The good news is that the buff isn't completely random-- in his testing Jagoex found that most of the time, the potion put a complementing buff on the player. That is, if the player has a Guardian Elixir buff, the potion would apply a Battle Elixir buff, and vice versa. He's only tried it a few times, so more testing is probably necessary, but there are indicators that the MAP's buff is not completely random.
Good news for Alchemists. This is definitely looking like a fun potion, and as long as it stays cheap, it could be a really useful for players who regularly need elixir buffs.
