Healing Pot and Arrow BOx (Also Anvil)

Lost_Legend means let more than one person at the same time use them so you won't get interrupted as much, but I don't think that's possible with the Warband system (where only one person can open the door or lift the ladder). That's why most maps have several pots/anvils/boxes.
