They removed that along with the teleport book in the magister bed room. Maybe +1 stat at the start of the game was considered too much for them, not to mention that if you do drink it before the Arena quest, the darn quest will still cleanse you of everything you have.
So yeah, that's either a nerf or a bandage fix to prevent you from running into that bug.
