|Skull Spellbook as found in the inventory|
The Skull Spellbook (name not official) is a Magical Weapon of the Spellbook category. Its Rarity is currently unknown.
Not much is known about the Skull Spellbook, it can be assumed that it is dropped by the Undead Mage. The Skull Spellbook is held in the Player’s right hand with the spell being cast in from the player’s left hand.
This book, as hinted by its motif, might have something to do with the Void element or Necromancy (however it can be assumed that the connection is more likely to the Void element as Necromancy is not a known topic in Hytale).
