What is book of darkness osrs?

The Book of Darkness is a powerful magic book in the game Old School RuneScape (OSRS). It is obtained by completing the mini-quest Horror from the Deep, and requires 70 Magic to wield. The book provides some magic attack and defence bonuses, and can be used to cast various spells.

One of the notable features of the Book of Darkness is the ability to store a selection of up to six spells from the standard spellbook. This allows the player to switch between spells quickly without needing to access the spellbook interface each time. Additionally, the book grants access to a unique spell, Claws of Guthix, which requires level 60 Magic and can hit up to 20 damage in PVP combat.

The Book of Darkness is a popular choice among magic users in OSRS, especially for Player versus Player (PVP) combat. However, its high requirements and limited availability make it a valuable and sought-after item among players.
