The Shaikahan

The Shaikahan is a lion-like creature which prowls the eastern jungle of Karamja and is involved in the Tai Bwo Wannai Trio quest, where the player must help Tamayu defeat it. The Shaikahan is immune to all damage except for karambwan-tipped spears, poison and recoil. These methods are the only way to damage the Shaikahan before and after the quest is complete. It has a unique drop of Shaikahan bones, which give 25 Prayer experience when buried.

 * The Shaikahan is one of three lion-like creatures in Old School RuneScape, along with Commander Zilyana's bodyguard, Growler, and the Sphinx located in Sophanem.
