Divining Rod

The Divining Rod is an item used for locating the Things. In Adventure Mode, the Divining Rod is in a Divining Rod Holder directly next to where you spawn. Once you "pick" the Holder, it will disappear a few seconds later. The sound the Rod gives off changes pitch and speed depending how close a Thing is. It also radiates rings of different colors, again depending on how far away a teleportato piece is.
