Tricky Items

Certain items in the game are good for you, but aren't explained in great
detail. Items that help you gather your spoils faster, items get get you from
point A to point B faster, items that enable PVP combat, and even items that
prevent pesky botters from stealing your kills and encroaching on your
territory while you do evil missions that take long enough on their own without
the assistance of cheaters.
