Tone down the frequency of vomiting darkness
Went through one level, exploring it fully without delays. 5 vomits of darkness during that time. That results in having a lot (virtually all) levels having black spots. Which is pretty annoying in the sense that you can't basically even face a rat pack from a wererat without it occurring at least once during that time, or run through levels you visit several times because walking is interrupted always in the darkness.
I understand if the target of the corruption is to be annoying and potentially dangerous, but please tone down the chances of it happening. Currently it's way too common. Make the dark spot larger then if that is needed for rebalancing.
This is especially tricky for chaos knights who start with that corruption. Basically every single place in the world is going to have a ton of dark spots.
