Lay Egg is a monster spawning ability of the Sand Maggot type of monsters. The giant insect adults will occasionally drop an egg on the ground where it will pulsate for a period of time before hatching into young.
This ability can quickly fill the battlefield with vicious reinforcements as soon as the eggs begin hatching, easily overwhelming an unprepared adventurer. Therefore it is advisable to kill them before they hatch.
In Diablo Immortal, Plague Nests and Broodmothers also have this ability.
