Biome Conversion Bombs are the way to go if you want to convert large sections of terrain to another biome fast. There are four types of Biome Conversion Bombs(hereafter referred to as BCBs); Green, Corruption, Jungle, and Hallow. Each one will turn a section of tiles with radius 75 into their respective biome(Green being the Overworld). These tiles are activated by wires, and will not hurt NPCs or the player when activated.
- When a BCB is activated, if a switch, pressure plate, or lever is on top of it, this tile will not be removed. (Version 16.3)
