Osiris is the boss of Duat, the secret area in the Temple of Anubis. He is the father of Anubis, and drops the Tablet Of Destiny upon death, a valuable item used to obtain the Qilin and reach the Sunken City.
Once the fight starts, he will start to float back and forth, stopping and slamming the ground anytime the player passes under one of his hands.
This destroys tiles, but his hands will not extend deeper than two tiles below the top of the Duat.
The top of the hands are safe to jump on, but being slammed by them will deal two damage and hitting the sides will stun the player and send them backward. They are primarily used as a way for the player to get within striking distance of Osiris himself.
It is possible to telefrag Osiris himself as well as both of his fists, leaving him with no method of attack. This is only possible if the player finds a Teleporter from a Crate, has The True Crown, or finds a Teleporter or Telepack encrusted in one of the tiles in the Duat, however.
- Although Osiris is a menacing figure, the largest threat in the battle of the Duat is Anubis II, who spawns shortly after Osiris and floats down from above. His power to summon coffins is significantly more dangerous than Osiris' fists, so it is highly recommended to get rid of Anubis II quickly. Letting him stick around can quickly lead to Osiris's arena getting overrun with enemies.
- As for Osiris himself, his pattern is very consistent and can be dealt with pretty easily, even without bombs and Paste. Causing one hand to slam down, then carefully chaining hops on it will allow the player to wail on Osiris's face with the whip as he floats back and forth.
- It is important to pick up the Tablet of Destiny as soon as it drop from Osiris; depending on where he dies, the tablet may fall into a lower section of the map with dangers such as enemies spawned by Anubis II, Apep, or most unfortunately, Lava.
- Players should be careful not to touch the black smoke on either side, as this will repel and briefly stun the player, which may land them below the arena where the Apep is.
