Corrupted Water is one of the many Liquids that exist in Creativerse.
It needs a Lumite Mining Cell to be foraged, which is currently the best Power Cell in the game and will still lose durability considerably when scooping up Corrupted Water. Be careful when doing so, because being close to Corrupted Water will trigger and slowly fill a corruption meter (scale) that will inflict corruption damage over time when filled completely, no matter in which biome the Corrupted Water is placed.
Corrupted Water does not have negative effects in any way if being carried in the inventory or put into a quickslot, neither will it cause any problems or changes when being stored in any containers.
"Natural" Corrupted Water can usually only be found on the Corruption layer underground on every Creativerse gameworld. There, Corrupted Water forms very large and sometimes deep lakes with many small islands formed of corrupted blocks and also corrupted trees - which makes it look much like a large corrupted swamp within a giant cave.
Corrupted Water can also be "produced" by players by throwing Corrupt Bombs at ordinary blue Water. Currently no other Liquid can be corrupted this way, and Corrupted Water also does not corrupt ordinary Water just by touching it (like it was in earlier versions of Creativerse).
This violet liquid can be deadly for player-characters and some Creatures (most common surface animals) because it inflicts corruption damage immediately when being touched, no matter how full or empty the corruption-meter (scale) on the screen might be.
However, creatures and player-characters won't die immediately even when falling into Corrupted Water. Instead, touching Corrupted Water will deal corruption damage over time that will usually last for about 2 seconds longer after leaving the Corrupted Water.
While Keepas of any kind seem to have developed resistance against Corruption lately, corrupted creatures (Corrupted Pigsies, Corrupted Leafies, Corrupted Mirus, Corrupted Chizzards and Things) seem to be completely immune to Corruption and such can swim through Corrupted Water completely unfazed. In return corrupted creatures are extremely vulnerable to Mineral Water and will quickly die when being made to touch it or wade into it.
Corrupted Water is useful for cooking certain kinds of Food in the Cooking Station, like Corrupted Soups, Corrupted Breads, Corrupted Sandwiches and Corrupted Pies. This Food can be fed to Pets, as some love these as their favorite fodder, and can also be consumed (by right-clicking a stack placed into any quickslot) so they will give player characters resistance up to immunity to corruption damage over time. Some types of Food will even reverse the damage over time that is inflicted by corruption into healing over time, which will make swimming through Corrupted Water safe, even though the corrupting effects will still be visible on the screen.
To reverse the effect of corruption damage into healing over time for 15 minutes, Corrupted Sandwich, Corrupted Soup or Corrupted Pie can be consumed. To cook these types of Food you will not need to unlock any specific recipes other than the basic ones (only 4 currently exist: Soup, Bread, Sandwich, Pie), as depending on the ingredients used, different types of Food can be created with only these 4 recipes.
Corruption Resistance Potions will reduce the corruption damage over time (inflicted when touching Corrupted Water and/or being hit by certain corrupted creatures) to half of it's intensity and will mainly negate the corruption scale/meter that shows up and is starting to fill itself with violet color when the player character gets and stays close to Corrupted Water (and/or to "natural" corrupted blocks).
Corrupted Water can be changed into healing Mineral Water by throwing Purification Bombs at it, or by placing Healing Beacons close to Corrupted Water for a short while. This change is a permanent one.
Corrupted Water can turn blocks of green Grass into Corrupted Grass and any kind of Wood (not Logs though) into Corrupted Wood (with two more specific sub-variants that look the same) when touching these blocks directly (not diagonally, but at least on one side) in the game world.
In earlier versions of Creativerse, Corruption had spread more aggressively and so Corrupted Water had been able to corrupt other kind of blocks like Dirt, Stone and Leaves too, while additionally to that also more types of solid corrupted blocks had the ability to corrupt other blocks as well.
