Corruption is sort of a poison or disease that can change certain blocks and liquids (Water) to corrupted variants. Corruption can also slowly damage uncorrupted creatures until they die, and can affect player-characters negatively in different ways.
Corruption currently (as of R27 in January 2016) can be found "naturally" on the Corruption layer underground, the deepest layer of any Creativerse-world as yet. Additionally to that some gameworlds also feature occasional corrupted wooden poles floating over oceans or surfaces at certain locations.
After obtaining corrupted blocks, player-characters can then corrupt or uncorrupt ("purify") a specific range of blocks and liquids in any other Biome and Layer where corruptable materials/blocks like green Grass or Wood (trees) are common.
Players can also place corrupted blocks anywhere - if a large enough amount of these blocks has been placed, corrupted creatures can spawn in random numbers on or close to the corrupted blocks in darkness, and sometimes perhaps also a Diamond Treasure Chest.
Getting too close to corrupted blocks will make a corruption meter show up in the UI above the health bar, just like heat and cold also have their own meters in Creativerse. This corruption scale will slowly be filled with purple color as long as the player-character is staying close to corrupted blocks.
The more corrupted blocks are close by the faster this meter will fill, no matter how close or if the player-character is touching the corrupted blocks or not (in distinction to earlier versions of Creativerse). When the corruption meter is completely filled with violet color, the player-character will start to take damage over time as if poisoned.
Moreover, if player-characters touch Corrupted Water (currently the only corrupted liquid) they will instantly take damage over time (and for additional 2 seconds after leaving the Corrupted Water), regardless of how full the corruption-meter is or was.
These effects can be counteracted separately.
To reduce the effect of corruption damage, Corrupted Bread can be eaten. To even reverse the effect of corruption damage into healing over time, other types of corrupted food can be consumed, like Corrupted Sandwich, Corrupted Soup or Corrupted Pie.
To make the corruption meter go down and vanish completely eventually, player-characters can either take quite a distance from corrupted blocks/areas or create a large enough uncorrupted area - like by throwing Purification Bombs. Else player-characters can also touch a Healing Beacon which will heal them up over time additionally.
However if player-characters leave these safe spots to venture into corrupted areas, the corruption meter will once again start to fill. To hold back the corruption meter from showing up (or making it vanish immediately) for a few minutes, Corruption Resistance Potions can be used.
Purifying Corrupted BlocksEdit
On the Corruption layer corrupted blocks can be purified either by Purification Bombs or Healing Beacons). Corrupted trees on the Corruption layer will then turn into Cragwood with Cragwood Leaves, Corrupted Stone will turn into normal grey Stone, Corrupted Dirt into common brown Dirt and magenta-colored Corrupted Water into healing Mineral Water.
Corrupting Uncorrupted BlocksEdit
Not many kinds of (uncorrupted) blocks can be corrupted currently (different from earlier versions of Creativerse):
- Stone into Corrupted Stone
- Dirt into Corrupted Dirt
- Water into Corrupted Water
- green Grass into Corrupted Grass
- Ashenwood into Corrupted Ashenwood
- Elderwood into Corrupted Elderwood
- Ashenwood Leaves into Corrupted Ashenwood Leaves
- Elderwood Leaves into Corrupted Elderwood Leaves
- by throwing Corrupt Bombs at the uncorrupted blocks.
All other blocks of Wood - Cragwood, Parchwood, Shorewood, Autumnwood, Wildwood, Weepwood - will all turn into ordinary Corrupted Wood. (And this Corrupted Wood will then ALL turn into Cragwood if purified again.)
The same thing goes for nearly all other blocks of Leaves. Cragwood Leaves, Shorewood Leaves, Autumnwood, Wildwood Leaves, Dark Wildwood Leaves, Weepwood Leaves will all turn into ordinary Corrupted Leaves when being corrupted. (And when purified again, they will ALL turn into Cragwood Leaves.) Parchwood Leaves cannot be corrupted, neither can any kind of Logs.
Despite some incorrect tooltips, Corrupted Grass, Corrupted Ashenwood, Corrupted Elderwood nor their leaves can be found anywhere on the Corruption layer but can only be "made" by players from uncorrupted blocks and do not occur "naturally" anywhere on any Creativerse-world currently (as of R27 in January 2016).
Corruption can "spread" by itself to uncorrupted blocks simply when corrupted blocks or liquids are touching certain uncorrupted types of blocks too, but only in a very limited way currently (as of R27 in January 2016), not as quickly as in earlier versions of Creativerse or in [Terraria] for example.
Current corruption-spreading-"rules" (as of R27 in January 2016):
- any kind of Wood-block (no Logs though) can be corrupted by letting it touch Corrupted Water, Corrupt Obelisks or any kind of solid corrupted block with one of its sides (not diagonally/just a corner) in the game world
- green Grass can be corrupted by Corrupted Water or Corrupt Obelisks if touched by that directly side-to-side(or on top/below (but not diagonally
- Corrupted Water cannot corrupt ordinary Water that is placed next to it, neither will Mineral Water become corrupted. Mineral Water cannot even be corrupted by Corrupt Bombs any longer (as of August 2016)
- common Dirt, grey Stone and uncorrupted tree-Leaves are not affected by "spreading" Corruption anymore - neither by placing Corrupted Water nor any kind of solid corrupted blocks onto or next to them. It needs Corrupt Bombs to corrupt Dirt, Stone and Leaves
These mechanics might be changed again in the future though, as corruption has been able to spread quite aggressively between more variants of blocks and liquids in earlier patches of Creativerse.
