The list of blocks that can be converted is much shorter.
Can corruption spread through granite.
Grass stone sand and ice.
This happens by the corruption slowly transforming the mud blocks into dirt and stone so the biome can spread through grass and stone blocks.
Mud will be gradually converted to dirt stone.
Corruption spreads through sand and stone and will slowly turn mud to dirt after the wall of flesh is destroyed.
Recently as of 1 3 the corruption can now spread through the jungle biome.
Now has own specific background.
Only the following blocks can spread the corruption crimson.
In practice it doesn t matter as the spread of corruption through stone and other blocks is faster than the growth of the bushes.
In addition to this remember that the corruption and hallow can jump three blocks to reach another block and continue spreading.
The only spreading tiles are corrupt crimson and hallowed grass and corruption and crimson thorny.
Crimson corruption will turn the mud to dirt and transform any sand or stone but it won t affect the mushroom grass itself.
Corruption and crimson can convert mud to dirt.
In a corruption cave some ebonstone created a spotty pattern on.
Dirt with grass on it.
No blocks will block the spread of corruption crimson.
Pre hardmode spread edit edit source.
In pre hardmode the three biomes can only spread in a very limited way.
On a related note hallow doesn t affect jungle grass but corruption crimson will.
Anything else is fair game.
Also most monsters appear to be worms as well as the boss.
It wouldn t be a bad idea to.
Absolutely everything else is neutral and won t convert either way.
An artificial corruption biome now only requires 200 ebonstone blocks instead of 500 blocks.
Now has a underground theme.
Hallow will affect sand and stone but leaves the mud alone and again won t change the grass.
The corruption biome can t spread through hallow and does not sourness the underground and carven enemies.
At hardmode it stands to reason that it still spreads as before but it s unclear whether it can now spread to rock due to the 3 tile rule.
Plants trees and vines can indirectly be converted when the blocks they re on get converted.
Note the inconsistency here.
Granite wood even stone brick any of these will work.
This allows it to spread into the cavern layer.
While crimson plants and vicious mushrooms are able to act as source tiles their corruption equivalents corrupt plants and vile mushrooms are not.
I e putting an uncorruptable snow block or two in between an ebostone block and a regular stone block will still result in the stone block.
Added to the game.
The monsters that you find in this biome at any time of day are relatively stable and acts as an excellent reason to avoid corruption at the beginning of the game.
