This mod adds needles to your compass that, within range, points to the ores you want.
Video example:
*It will _not_ point to diamonds "above the ceiling" or "below the floor". If you really want to clean out an area, you have to run through it in different heights.
You can basically make it find any ore you want, also it points to dungeons.
o: is that music part of the mod? xD. thats sick whoever thought about that. but like the guy above me said, its pointless. just use inv edit or something like that
