Nezikchened

Nezikchened is a level 187 black demon that you fight at three different times in order to complete the Legends quest. He can drain your prayer to 0. Like all demons, he is also weak to Silverlight, Darklight, and holy water. He cannot be fought outside the Legends quest. He has a very peculiar habit of calling you 'Vacu'. Vacu meaning vacuous, which means having a lack of thought.

First battle
Nezikchned has possessed Ungadulu, the shaman of the Kharazi Jungle. Players must use the book of binding of him to reveal his true form. He will then drain the player's prayer and use melee on them. He can be easily defeated if they drink a prayer potion and then use protect from melee. Stabbing him with Silverlight or throwing a vial of holy water at him can weaken him.

Second battle
Players will fight him again after doing the obsidian dagger part of the quest. He drains the player's prayer unless they use the holy force spell card on him. He uses a weak magic attack at first, realizes it's not doing any good, and then switches to melee.

Final battle
At the end of the quest, players must fight the demon one last time. He uses a powerful magic attack and melee, and he drains prayer at the beginning. A possible way to defeat him involves drinking a prayer potion, using protect from magic, and hiding in the trees with a ranged weapon.
