How to Get The Book of The Dead

Unlocked at Level 1

Starting at level 1 you can already access the Raise Skeleton skill which allows you to raise Skeletal Warriors to a specific number which you can increase through Aspects.

Golems Unlocks Starting at Level 25

Once you reach level 25, you'll be able to unlock the next component of the Book of the Dead to unlock the Golem skill. This is a separate skill from Raise Skeleton that summons melee skeletons and skeletal mages as this is a skill that allows you to summon a golem that can deal massive amounts of damage and tank strong hits without dying!

How to Use The Book of The Dead

Upgrade Summons to Enhance Their Abilities

The Book of the Undead allows you to choose one of two upgrades for your summon sub-type, granting them buffs and abilities to enhance their prowess and utility.

Sacrifice Summons for Permanent Character Buffs

The Book also allows you to sacrifice a summon sub-type in exchange for permanent buffs for your character but you will no longer be able to summon that type.

For example, sacrificing a Reaper grants you a permanent increase in shadow damage, but you will no longer be able to summon Skeletal Warriors.
