The caster tears down the walls between realities, and a black cloud of roiling energy sweeps across the battlefield. As the darkness travels, slimy tentacles lash out from its depths, dragging unfortunate victims screaming into one of the infernal regions and an unknown fate.

Arnzipal's Black HorrorURL Copied!
Remains in play. Arnzipal's Black Horror is a magical vortex that uses the small round template. Once the template is placed, the player then nominates a direction in which the Black Horror will move. To determine how many inches the template moves, roll an artillery dice and multiply the result by the caster's Wizard level. Any model touched by, or passed over by the template must pass a Strength test or be slain outright with no armour saves allowed.
If the result on the artillery dice is a misfire, centre the template on the caster and roll both a scatter dice and a D6. The template moves a number of inches equal to the result of the D6, in the direction shown on the scatter dice (if you roll a Hit!, use the little arrow shown on the Hit! symbol). In either event, in subsequent turns, the Black Horror travels in a random direction and moves a number of inches equal to the roll on an artillery dice. If a misfire is rolled in subsequent turns, the Black Horror collapses in on itself and is removed. A particularly brave Wizard can infuse Arnzipal's Black Horror with more power, so that it uses the large round template instead. If they do so, the casting value is increased to 25+.
