I Like Your Hat
Terrarian
I'm someone who likes to cleanse my world completely or atleast limit where the evil biomes go so a gadget telling me how many evil blocks are around me in a clentaminator range would be awesome. The gadget would be sold by the Traveling Merchant for about 1 platinum and would be in the rare section of the sold items much like the pet items. The status message would be: There are no Corruption/Crimson blocks around you, There are X Corruption/Crimson blocks around you.
