Medicinal Grey Omen is a medicinal resource in Horizon Zero Dawn. It is used to refill the Medicine Pouch and restore health.


Medicinal Grey Omen is a medicinal fungus that can be found growing in underground or enclosed locations such as Cauldrons and Ruins. It is the primary medicinal resource that can be found in these areas.

Its base medicine pouch gain is 20%. As of the installation of The Frozen Wilds, it no longer restores the most amount of health out of all available medicinal resources, having been overtaken by Medicinal Fresh Salvebrush and Medicinal Thaw Omen. These, however, are exclusive to The Cut, where Medicinal Grey Omen cannot be found.
