Waystones

Waystones allow players to setup teleport points around the world in an adhoc fashion. A waystone is made up of a lodestone on top of a emerald, diamond or gold block.

When right clicking on the lodestone with an empty hand, a player will teleport around the nearest waystone that is sitting on top of the same block, up to 4000 blocks away.

You are not guaranteed to be teleported to a safe location so be wary of others creating waystone traps.
