Imp-losion

Imp-losion is a rare warlock spell card, from the Goblins vs Gnomes set. It deals damage and summons 1/1 Imps.

Strategy
At an average of 3 damage + 3 Imps, this card is barely mana-efficient, so Spell Damage is highly recommended. Be aware that the summoned Imps are very vulnerable to AoE attacks such as Holy Nova, Consecration and Wild Pyromancer.

This card works very well with Knife Juggler, for 2-4 extra knives. This essentially doubles the damage output of this spell, although the targets of the knives are not controllable. In this case the sequence of events will be: the spell deals damage; the Imps are summoned, one at a time, each followed by any events triggered from its summoning; then finally any deaths are resolved. Note that the Imps will be summoned before any deaths from the spell's damage have resolved, meaning that Deathrattle summons such as Harvest Golem's Damaged Golem will not appear on the board until after the Imps' summoning and related effects like Knife Juggler have resolved.

Known bugs
This spell will generate golden Imps if the target character is golden, even if the Imp-losion is not. For example, using a regular Imp-losion on a golden Sheep will produce golden Imps. This is a known bug.

Trivia

 * Original to Hearthstone, this spell has since inspired in World of Warcraft. Added almost two years after its Hearthstone counterpart, the spell is a Demonology warlock talent, with the text, "Demonic forces suck all of your Wild Imps toward the target, and then cause them to violently explode, dealing ... damage to all enemies within 8 yards." In contrast to the original card's single target damage, the talent is used to deal strong burst damage to multiple targets, making it the preferred AoE option for that tier.
