Sinister Offering is a spell within the Arceuus spellbook that requires level 92 Magic and the completion of A Kingdom Divided to be cast. When cast, the spell instantly offers up to three bones in the player's inventory, granting 300% the normal experience for burying them. Players must have level 70 Prayer in order to offer superior dragon bones via the spell, attempting to do so without 70 Prayer gives the message You require a Prayer level of 70 to do that.. Players may only cast offering spells once every 5.4 seconds.

The spell also restores one prayer point for each set of bones converted; for Ourg, dagannoth, hydra, and superior dragon bones, two prayer points are restored instead.

The spell can be cast without runes at the Fountain of Rune.
