Soul Seer

The soul seer is a useful redstone component. When powered or clicked, it make mobs glow in a 24 block radius. The type of mob is based on the block beneath the soul seer. A full list of these blocks can be found in this guide.

It can also be used as a mob detector. The comparator output of the block represents the number of mobs it highlights. If you placed tinted glass on top, it will only give comparator output and will not make any mobs glow.

It's crafted with sculk, making it a useful reward for looting the deep dark.
