Patch 5.0.4 - big changes in advance of MOP

[kandrathe]

Oh, another thing. Poisons are no longer "items" you apply to weapons. They are more like a spell you cast with a pull down similar to the other "choice" spells (call pet, summon demon, totems, etc.). All poisons in your inventory will be gray items. My understanding is that you can choose two poisons. They still need to be re-applied every hour.

There are two different categories: Lethal and Non-Lethal. You can have 1 Lethal and 1 Non-Lethal poison activated at any time, but you cannot have more than one of any individual poison category. If you activate a lethal poison and you already have another lethal one active, it will overwrite your existing lethal poison.
