The Manifestation of Zeal is the ultimate sign of religious favor with an Avatar in Conan Exiles. This item is used across all religions in Conan Exiles to upgrade altars/shrine and to summon Avatars.

This item cannot be removed from that altar/shrine it was crafted in. It's also obtained by crafting any of the religious items at the altar/shrine. As an example, for Mitra players can collect lingering essence and craft offerings of Mitra in for each manifestation of zeal, but they can also craft ambrosia with the same lingering essence and get a Manifestation of Zeal along with it. They have to collect the lingering essence from dead humans.

Regardless of the religion, they all require butchering human corpses and doing something with the byproducts as a primary way to make Manifestations of Zeal. Or players can mass produce the religious tool, such as the Mitraen Ankh for example.

Players will need to craft the tool for their religion to gather the special product from corpses. As an example, the religious gathering tool for worshipers of Mitra is the Mitraen Ankh. Players simply need to swing their religious tool at a human corpse to collect one of their religion-specific human resources. Slaying non-believers is the intended way to gain favor with the avatars in Conan Exiles.
