Callisto is an enormous bear that resides south of the Demonic Ruins, and is notable for being the only monster to drop the Tyrannical ring and the Callisto cub.

When fighting Callisto, use Protect from Melee and go into melee distance. Callisto has a powerful shockwave attack that cannot be avoided, dealing up to 60 damage each time he uses it. As he only uses melee, he will use this attack far more frequently if no one is within melee distance of him. The projectile of this attack is similar to that of Wind Wave. Callisto can also roar at his current target (and those next to them), causing them to be launched away from him for 3 damage. Players are unable to eat when they get launched and Callisto will tend to use his shockwave as a result.

The most convenient way of getting to Callisto is to use the Annakarl teleport tablet, purchased from the Bounty Hunter Store, or 2 law and 2 blood runes to cast Annakarl Teleport, an Ancient Magicks spell requiring level 90 in Magic. However using a waka canoe from Edgeville (requires level 57 Woodcutting and an axe) is also a viable method.

Players who intend on fighting Callisto should only bring items that they do not mind losing.

  • Callisto is named after one of the Greek god Zeus' many lovers, who was turned into the constellation Ursa Major.
  • Upon release, Callisto had a slightly worse drop table. In addition, players could exploit his low Magic by safespotting him with the trident of the seas behind a cluster of skeletons north of him. The cluster of skeletons have been removed with a normal update.
  • Callisto is the name of one of Jupiter's moons.
  • His examine text is a reference to Goldilocks and the Three Bears.
