Miazmur Egg
Miazmur Egg is an uncommon throwable item.
Can be used to spawn an elemental called miazmur - an enchanted anomaly elemental.
These “eggs” are really just highly incubated versions of creatures, used by altas during research, often for simulation purposes, which is why they tend to be friendly to their owner.
