Imp (Diablo III)

"Demons have been known to devour their own young when no other nourishment is available. Their offspring, the imps, sometimes manage to flee and band together with other demonspawn. They rove in vicious packs, ready to descend upon the unwary traveler and rip his body to shreds with their tiny, needle-sharp teeth."

- Deckard Cain

Imps are a type of demon.

Diablo Immortal
Dust Imps are encountered in Diablo Immortal, in the Library of Zoltun Kulle, and Shassar Sea. A variant called the "Demon Imp" is encountered in the Domain of Horror.

Diablo III
Imps appear in of Diablo III. They are tiny creatures and are never encountered alone. They move about at great speed, making it hard to catch them.

Imps lack special abilities or spells, but can cause damage in melee range with their sharp fangs.

Imps often be encountered in dungeons. They can also spawn from the bellies of Harvesters.

Individual Imps are, like most monsters, hardly a threat, but in numbers they can prove dangerous. Imps are relatively weak and lack special defenses, so a few hits often suffice to kill them and send their brethren scurrying.

Dust Imps
"Not all dangerous demons are large and imposing. The Dust Imps are little more than children in size, but they possess the cunning and bloodlust of far larger creatures. They take cover in the shadows, emerging only when viable prey wanders too close. Then they ambush leaving little more than bones behind them."

- Deckard Cain

These are the variant of the Imps, encountered in the deserts of Kehjistan: most notably in Desolate Sands. They have similar abilities, but may hide beneath the sand to ambush the player or to hide from damage. In Archives of Zoltun Kulle, the Arcane Constructs may summon them in large numbers, usually until the device is destroyed. After death, they crumble to dust, unlike the normal imps, which are of flesh and blood.

Vault Peons
Peons encountered in The Vault are modeled after Imps, and have similar traits.

Trivia

 * There is an achievement for knocking back five imps with a single cast or attack, a possible reference to Game of Thrones series and/or the Dungeon Keeper game (where slapping imps is an actual game mechanic).
