Illusion mages in fantasy novels are so lazy and uncreative, they all just be making clones and stuff. They should be out there creating pure nightmare fuel and impossible geometry that makes combat impossible.

Just thinking, but why has no one invented a term for mana sense? Like we don't call things sound sense, we call it hearing. It's smell, not scent sense. We made up the word mana so why have I never seen anyone make up a word for mana sense?
