  • This spell has two steps:
    • First, it deals its area of effect damage to all enemy minions, queuing and resolving triggers in order of play (see damage for details);
    • Then, it summons a random 1-Cost minion, queuing and resolving triggers.


A superior version of the mage's Arcane Explosion. The boardwide damage effect is even better on a Shaman, as they have easier access (albeit mostly random) to Spell Damage bonuses via the Wrath of Air Totem. The additional 1-cost minion is also a big nuisance for enemies.

Maelstrom Portal is a great early-game play and stifles aggressive enemies, but with Spell Damage it can create a huge tempo swing late-game as well. Against pure control decks, it can be used at will simply to summon a minion.

Possible summons[]

The following table lists all collectible 1 mana minions, reflecting the range of possible minions summoned by this spell.


This spell represents one of Karazhan's many "precisely calibrated portals attuned to a variety of exotic locales" - in this case, the Maelstrom, the former location of the Well of Eternity before it was destroyed in the Great Sundering. During the Black Empire, it was also the location of Y'Shaarj, the most powerful of the Old Gods.

The portal itself is found at the top level of the tower, which also features as the fifth wing in One Night in Karazhan - The Spire.[1]

In World of Warcraft[]

The Maelstrom Portal in World of Warcraft

Following Deathwing's reemergence into Azeroth, heroes of the Alliance and the Horde travelled to the Maelstrom to assist Thrall in attempting to seal the rift between Deepholm and Azeroth. A portal to the Maelstrom was briefly to be found in the capital cities; after journeying to Deepholm the portals were redirected there.

The Maelstrom is the gigantic rift that was created when the Well of Eternity collapsed into itself during the Great Sundering. Located in the middle of the Great Sea - which the Great Sundering created - the Maelstrom appears as a massive, fierce vortex of water.
