Repelling Candle

The Repelling Candle is an place-able item that prevents mobs from spawning on your island within a radius of 10, 50, or Infinite blocks. The crafting recipe for this item is unlocked at.

Usage
When you place down the Repelling Candle, you can prevent monsters from spawning on your island, within a range of 10 blocks, 50 blocks, or on the whole island. To configure its settings, right-click on it, and you will be able to choose your preferred color, effective radius, and toggle the particles ON/OFF.

It is also very useful if you wish to cull mobs, but also leave your biome unaltered, as previous solutions would often use a Nether Biome Stick to make the hostile mobs into Chickens.

NOTE: Placing the candle on a bottom half slab will cause it to turn into a normal torch and the candle will be gone.

Trivia
There appears to be a Repelling Candle in the Catacombs Entrance (Zone) in the Coal Mine. There is currently a bug where the Repelling Candle is able to be placed in the Hub. The bug happens if the player clicks on a crafting table with the Repelling Candle in their hand.
