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.

Combat characteristics
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). The Pain Elemental can bite but the bite does not do damage to the player.

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. Unlike the Cacodemon, which leaves behind a rather impressive corpse, the Pain Elemental when killed gives a grimace and explodes, leaving nothing behind (except Lost Souls).

Tactical analysis
Pain Elementals are about the same speed as Cacodemons, and have a similar pain chance and hit points, but are much more dangerous. Unlike the Cacodemons, whose attacks may simply be dodged, Pain Elementals release projectiles which will come around for more attacks and which will not disappear until killed. As such, it is vital to focus one's attention on the Pain Elemental itself as much as possible. Only once it is dead is it recommended to begin killing the Lost Souls.

Appearance statistics
The IWADs contain the following numbers of Pain Elementals:

Doom 64
The Pain Elemental appears in Doom 64 with an altered design. It is colored red (like the original Cacodemon while the Doom 64 Cacodemon was colored brown and had two arms), has a green eye and in place of its arms are two mouths so it can now spawn two Lost Souls at the same time. Its back has a large horse-like mane.

Doom RPG
The Pain Elemental appears in Doom RPG as a class of monster. There are three variations, identified by color:


 * Beholder (green)
 * Rahovart (blue)
 * Pain Elemental (normal colors)

They, however, do not spawn Pain Elementals when they attack; only when they are killed.
