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 three times the normal experience for burying them. If converting superior dragon bones, players will require level 70 Prayer to offer them via the spell. Players may only cast offering spells once every 4.8 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.
