We all know what Darkness and Blind does. However, I feel that the current Darkness should be renamed as Blind and vice versa. When you get blinded, the screen brightness turns to zero, making the screen darker. When you get the darkness status effect, you can only see a limited distance, which fits a bit in with bad eyesight and thus blindness. Somewhat trivial, but simple. Makes it less confusing for everyone as the name would actually makes sense.
