Corruption, conversion: When building this tower towards a non-darkness tower, they have a (0.25%?) chance to gain darkness element. If it succeeded, this tower disappears from tower tab. If it fails, then this tower returns to tower tab and deactivates from being used for (?) waves.

Darkness always has the corruption magic, and I only saw lucifer being corrupted in the game. Also imagine this card with Abyss king stat increase. Does dark forge items also counts as corruption too?
