(*)Level I and II creatures will not attack unless attacked first. (necessary to check up)
(**)If yes, right clicking on the creature will cause you to chase after it and place it in your inventory. Generally, the corpses of such creatures cannot be lifted, but those of larger creatures can.
(***)Milk and wool can only be obtained while the creature is alive. To obtain the hide, one must first skin the corpse before butchering it. Intestines and meat are obtained upon butchering the corpse. After butchering the corpse, bones (and similar objects) are left on the ground and can be picked up. Silkworm eggs are acquired through a unique process (see the object's page for details).
(****)If one member of the herd is provoked, the entire herd will attack.
Other creatures include the barmaid and the character generation NPCs.
