Kemet: Blood and Sand – Book of the DeadExpansion

From BoardGameGeek:

In Kemet: Blood and Sand, the gods of Ancient Egypt war with each other in epic battles using every tool at their disposal. Some are even willing to consult the Book of the Dead, seeking forbidden knowledge of the Beyond, and the ability to call upon darker, more powerful, and more dangerous powers… Thanks to the Book of the Dead expansion, you have access to some of the most powerful power tiles in the entire Kemet: Blood and Sand universe. However, access to this terrifying knowledge comes with a cost, as you will have to sacrifice your units to feed the Beyond. By doing so, you'll sink into putrefaction, lose more and more prestige over your opponents, and even part with your precious victory points. This is the price to pay for access to such fearsome abilities and the most frightening of possibilities. Perhaps you will learn to summon the monstrous Apophis, a being of pure evil that dwells in the Underworld. Perhaps you can bend the all-knowing Thoth, the repository of the dark knowledge, to your will. If you are prepared to pay the high price for consorting with such dark forces, they will be formidable allies in your conquest of the black lands of Kemet: Blood and Sand. -description from the publisher
