Clash of Clans: Dark Spell Factory

The Dark Spell Factory allows the player to create Dark Spells using Dark Elixir. There are currently three Dark Spells: the Poison Spell, Earthquake Spell, and Haste Spell. It was released on the update that came at July 1, 2015.

All existing dark spells take up one housing space in the spell storage, whereas elixir spells take two spaces. The total spell storage capacity is shared between the Spell Factory and the Dark Spell Factory. The Dark Spell Factory adds one spell storage capacity to the total spell storage capacity.
