The Ancient Guthix Temple is an ancient temple devoted to Guthix found in the While Guthix Sleeps quest. To access it, the player must have a sapphire lantern. If the player goes to the Tears of Guthix cavern, one of the light creatures can be attracted to the player, who can then ride the creature down the chasm and to the temple.
During the quest, the player, pretending to be Surok Magis in order to get past Movario and Darve, goes into the temple and must open an ancient huge door within this temple guarding the legendary Stone of Jas by solving a puzzle concerning Herblore.
The Stone is protected by the Balance Elemental, a Guardian created by Guthix. It has remained there for centuries but during the quest is stolen by Lucien, a Mahjarrat who also possesses the Staff of Armadyl.
After While Guthix Sleeps, players can return to the temple to fight tormented demons. If a player has access to the Max Guild boss portal, they can easily get back to the temple. The player may direct the portal to tormented demons for 100,000 coins. After going through the portal, the player will arrive in the centre of the the cavern, just before the door of Guthix and near the stone table; a short walk away from the tormented demons. If the player does not have access to the boss portal, the next fastest way is to teleport to the Tears of Guthix cavern with a games necklace. Then the player will have to attract a light creature and go into the chasm. Once in the chasm, go south, climb the wall twice, go through the cave opening, and take the south path to reach the tormented demons.
- When a player was at the entrance to the temple, the air key, water key, earth key and fire key could be seen floating in the blackness near the temple, easily visible on the minimap. These were removed in an update.
- When going down the chasm, during the cutscene there is a cave goblin attempting to go down to navigate the chasm under Moravio's orders. This still occurs even after the quest is completed, and may be an oversight by Jagex.
