I was thinking just one item to do all that but you know, I can see myself using the keg item for my party. I can already hear the snickers ripple through my family over a party effect keg item - well unless they called it a barrel.
Maybe I was to greedy in my wish. ^^; One item to do all of that would end up in the epic food line, wouldn't it? So I would settle for a drink that gave both regen and refresh and if it could effect the entire party I would be very happy.
