Book of Lifesteal

The Book of Lifesteal is a drop from The Doom. It is a very unique item which functions unlike any other in the game, having a charge function. It does not function using mana, but it still is an item that requires a different charge.

The charge is unique to this item, and it is displayed on the Book of Lifesteal's icon in the inventory/hotbar. When the item is held, it also shows the charge time under the mana bar. (To the left of the mana if the inventory is open)

It charges by 1 each second, and every 30 seconds it is usable. Using it inflicts the Life Thievery buff, which allows the player to recover health the same way as Vampire Knives using any weapon. The buff lasts for 10 seconds, and the player can heal up fairly well using this item when in peril.
