Pain elemental

The Pain Elemental is a monster in Doom II. Similar to Cacodemons, they float, have a single eye and a large mouth. Pain Elementals also have small arms although these are not used for anything. Instead of shooting a standard projectile, Pain Elementals shoot Lost Souls. Because of this, they will never be targeted by another monster, though it is possible to have them target another monster (although the Lost Soul fired does not inherit the Pain Elemental's target).

When killed, the Pain Elemental will spawn 3 more Lost Souls unless the Lost Soul limit is in use and has not already been reached.
