The Blight

The Blight is a bio-weapon biome created by throwing down a Blight Bottle. It features mostly shades of purple. This biome spreads quite fast and has 3 stages of infection. First stage of infection slightly tints the infected block purple, takes 25% longer to mine and takes 15 minutes to infect a new block and to upgrade. The second stage is a slightly stronger tint of purple, takes 50% longer to mine, takes 10 minutes to infect a new block, 15 minutes to upgrade and can only upgrade within 25 blocks of a third stage infection. The third stage of infection heavily tints the color of the block purple, takes 100% longer to mine the block, may spawn a Parasitoid (25%) and takes 5 minutes to spread, but it can only upgrade if it's close enough to a Blight Spore. Every attempt of curing the infection will take away only 1 level, so it may require you to disinfect a block 3 times. The blight can only infect organic blocks including blocks infected by the hallow, corruption and crimson. It also cannot infect dungeon bricks, lihzahrd bricks, ash and ores. To prevent spreading, a wall has to be at least 3 blocks thick. This biome also features almost no monsters, but is still very dangerous. Stepping on a blighted block, even a stage 1 block will inflict you the Blighted debuff until you step off the blocks. However, if a monster touches a blighted block, he will be debuffed until it dies and if the monster dies on a stage 2 or stage 3 blighted block, all its health will be transferred to the spore and all its structures. If a monster gets eaten by a Feeder, it will transfer twice the health to the spore. This biome can also be used to defend your base, however it is very risky and may end up infecting your entire base if not tended to properly. The blight can even be weaponized.
