The compass is a tool used in Survivalcraft to help you find your way back home when you stray off too far.
Description (From Recipaedia)
Compass points to the location of the place of last sleep or to the nearest magnet, if present. It is indispensable when finding your way home on far away journeys.
How Does The Compass Work?
The compass needle will point to the location of the nearest magnet. If no magnets have been placed in your world, the needle will point to your last sleeping spot. And if you have just created a new world and not yet slept, it will point to the shore where you first spawned.
Requires 1 diamond and 4 copper ingots. You get one compass.
