Anti-Crystal Area

An «Anti-Crystal Area» is a rare trap in Sword Art Online.

Background
An Anti-Crystal Area is a rare trap that is sometimes activated in random dungeons and boss rooms starting from the seventy-fourth floor. As the name suggests, this kind of trap prohibits that use of crystals, disabling the players from teleporting and healing themselves with crystals in battle. While crystals can not be used, other items such as healing potions can be used but those take longer to use.
