With no light sources, this corruption can become very annoying and the player might want to get rid of it as quickly as possible. It is especially dangerous in places where there is no reason to cast Darkness anyway — such as Terinyo or Dwarftown where the PC can thus accidentally attack unseen civilians, or in shops (unless the PC is shoplifting anyway). Chaos Knights who begin the game hating the sun are not especially disadvantaged, since they have little use for Terinyo anyway.
Whilst fighting monsters that can't see in the dark certainly has advantages, most PCs (except Barbarians and Mindcrafters) have little problem learning the corresponding spell to cast it at will anyway. Can be extremely dangerous (deadly) to doomed characters.
