Now what's that skill called... ahh yes, warcraft.
I always thought the point of this skill was to make it possible for knights to pick certain poisons themselves, negating the need to use shops, and isn't it just possible to trade comms with people who've got ult poisons to get the others.
Just a thought for you shopaholics out there
