"Flesh Spawners are the weakest of the Vile Mothers, but their ability to spawn a Flesh Beast means they can quickly build a horde of assailants."

- Monster summary(src)

Flesh Spawners are an Vile Mother type. They can be found spawning Flesh Beasts in:

They spawn a maximum of 16/17/20 (depending on difficulty) Flesh Beasts with a limit of 5/5/6 at once. It is difficult to kill them if there are a number of them in one area because they are constantly spewing Flesh Beasts. Kill these first so no more Flesh Beasts attack you.
