Hags can perform a ritual to create an ooze that incorporates a hag eye. Known as a hag eye ooze, these creatures serve as covert, autonomous surveillers. They are prepared by cooking a putrid mixture of nutrients and reagents for up to two weeks, then adding a hag eye, although the period can be shortened considerably by working as a coven.1
A coven ooze forms when a hag eye ooze combines with multiple hag eyes, whether already formed or created by it from the latent magic and an eyeball from a dead hag. For instance, coven oozes might form when a hag coven is destroyed while a hag eye ooze remains close by. Coven oozes can also consume hag eye oozes, and consuming new hag eyes by any means increases their size to potentially massive proportions.2
