This data pack makes it so that ringing a bell while certain blocks are above it or holding specific items will cause it to highlight different mobs whenever it is rung. Useful for when you're searching for unlit caves, or trying to find that nearby zombie that keeps annoying you with its growls..
Highlight Details:
By default, the highlight is triggered when a valid mob for the item/block is detected within 32 blocks, causing all valid mobs within 48 blocks to be highlighted. These distances can be doubled by holding a Nether Star in the offhand.
