So I posted one suggestion here yesterday about an item that tells you where a Crimson or Corrupted block is and in what direction. A lot of the comments said that they would rather have a potion or item that showed the blocks like a Spelunker potion. I thought about it, but then I thought that if you were to go on a cleansing adventure and spend an hour or two trying to get rid of the disease, then I think crafting the same potion again and again might be a much. Then I thought “The Clentaminator sure does look like a sniper gun. But you know what its missing? A scope.”
(Also at one point Redigit responded to a mention in the comments of the OG post and said they already added something better, so who knows Evil and Hallow Biome Spelunker potions might be a real thing)
