Imp

The Imp is a small humanoid demon, the most common monster encountered in id Software's IWADs. He is brown in color, with red eyes, a few white spikes on his body, and noticeable white claws on his hands and feet.

The Doom instruction manual says:
 * You thought an imp was a cute little dude in a red suit with a pitchfork. Where did these brown bastards come from? They heave balls o' fire down your throat and take several bullets to die. It's time to find a weapon better than that pistol if you're going to face more than one of these S.O.B.s.

Combat characteristics
An Imp attacks by ejecting a single fireball, which does not inflict blast damage. At melee range, he employs a clawing attack.

Tactical analysis
The Imp moves slowly, as do his fireballs. The player should practice until evading both sorts of objects becomes completely straightforward (except perhaps under highly unusual circumstances, such as a teleportation trap in close quarters).

An Imp can be killed by one shotgun shell (usually) or six bullets (often). As the above quotation implies, facing down multiple Imps with a pistol takes concentration, but it can be done, given sufficient maneuvering room and adequate footwork on the player's part. In fact, the Imp's relatively high pain chance sometimes makes it difficult for him to retaliate at point-blank range.

Imps often come in packs, and the super shotgun is particularly effective here. While the standard shotgun is not completely reliable as dispatching one Imp with one shell, a blast from the super shotgun usually brings down two and in rare cases even three.

Melee against an Imp should usually be avoided as it is much trickier than against a Demon, as the Imp is much more adept with his clawing attack than the generally more oblivious Demons. The chainsaw takes a short while to dispatch an Imp, not much trouble if just one, but the player risks being surrounded if there are several. If the encounter takes place in a large open area, hit-and-run tactics with the berserk fist are effective, running up to the Imp to throw a punch and then quickly retreating, essentially similar tactics to the shotgun such as circle-strafing.

Although his ranged attack and hit point total give him some purchase against zombies, the Imp can easily find himself overmatched in monster-monster battles. A single Imp fighting a sergeant has cause for optimism, but a Demon or Spectre can almost always outslug the first two or three Imps he engages in melee, and two blows from any larger monster is normally too much for an Imp.

Imp fireballs move 50% faster than normal when the Nightmare! skill level or the -fast command line parameter is used.
