Gemkeeper

'WARNING: This game is not for the faint of heart. The Gem Keeper will spawn at random locations, and may scare the player.'

The Gem Keeper is a being located in the temple. It spawns after a set period of time (5 minutes in easy, 3 in medium, 2 in hard) and its only objective is to eliminate the players before they can escape.

Notes  Strategies 
 * The Gem Keeper is designed to keep you from acting lazy; it tracks you down.
 * It will not kill you if it goes through your head.
 * If the Gem Keeper is active, try to focus on stealing relics and gems only if they're wandering in the main room, as they take a while to do this.

While attempting to steal relics or gems, make sure to check for the Gem Keeper down the halls. You can tell where the Gem Keeper will spawn determined by the torches turning purple. If they pick a hall, they'll spawn where the relic would be, and make their way through it. If they decide to target the main area, they'll usually start from the spawn area and make their way to the exit.

-

Be careful; if the Gem Keeper is chasing after you, do not walk. Sprint, and proceed to the exit.

Don't be afraid to reset. You may lose your gems, but it's better than losing the game.

You cannot attack the Gem Keeper.
