The Player Compass is a tool from Witchery. This tool is used to track player locations in a similar manner to the Vanilla Compass. It can be shapelessly crafted with a Taglock Kit in order to bind it to a player or creature.
Bound players that are logged into the server and in the same dimension will be pointed to by the tool's icon. If the bound player is not logged in or in the same dimension as the user, or the creature bound is not a player, it will spin randomly.
