Invisibility is one of the most useful items when facing the hordes of monsters in any Gauntlet. While invisible, a hero can run around completely undetected by monsters who will ignore the presence of that hero. It has many uses, allowing heroes to obtain items, get out of a horde, race to an exit, or simply thin the hordes without fear of retribution. Monsters will immediately disengage if a hero suddenly goes invisible. Don't get too complacent, however; while having a short breather can be nice, turning invisible doesn't render a hero invincible. Invisibility runs on a timer.
As in Legends, but the list of unaffected monsters grows to include Gargoyles.
