Lost soul

The lost soul is a flaming, flying skull first introduced in Doom's second episode, The Shores of Hell.

Doom II made additional use of the lost soul by utilizing it as the projectile attack of the new pain elemental monster. The Doom manual gives this description of lost souls: "Dumb. Tough. Flies. On fire. 'Nuff said."

Tactical analysis
The player can stop a lost soul's charge by shooting it while it is attacking. Because of their 100% pain chance, it is often safer to use the pistol against them, rather than the slower-fire shotgun, so the lost soul will not have enough time to retaliate. Also, lost souls will stop when they cross an object in their charge path, such as a shotgun or a medikit, which stops them as if the objects were a wall. Using rockets against groups of lost souls is hazardous, as there is a considerable chance that a Lost Soul will suddenly fly towards the player, causing one of the rockets to explode close to the foolish marine, causing serious blast damage to the player.

One unique characteristic of lost souls is that after they attack, they do not retain their target, and instead pursue the player, unless hurt by their previous target. This makes them somewhat unreliable when a player provokes and attempts to sustain monster infighting, or at least unpredictable in such situations.

Data



 * 1) This table assumes that all calls to P_Random for damage, pain chance, and blood splats are consecutive. In real play, this is never the case: counterattacks and AI pathfinding must be handled, and of course the map may contain additional moving monsters and other randomized phenomena (such as flickering lights). Any resulting errors are probably toward the single-shot average, as they introduce noise into the correlation between the indices of "consecutive" calls.
 * 2) Assumes that direct hits are possible, which does not occur in any stock map.

Appearance statistics
In classic Doom, the lost soul is first encountered on these maps:

The IWADs contain the following numbers of lost souls:

Doom RPG
In Doom RPG, the lost soul appears as a class of monster. There are three variations, identified by color:


 * Phantom (green)
 * Lost soul (normal colors)
 * Nightmare (blue)

Lost souls can move three panels in a single turn instead of one, and will attack automatically once they are in an adjacent panel to the player, even if it has already moved. It attacks three times consecutively and can be damaged by the fire extinguisher.

Doom 64
These variations of the lost souls look somewhat different and there is fire only on the top of their skulls.
