Warhammer: Storm of Magic (2011)

[Publisher website]
Storm of Magic is an expansion for Warhammer, the Game of Fantasy Battles. Launched in July 2011, Storm of Magic describes what happens when great eldritch maelstroms roil across the lands. Magic becomes far more powerful and there is a whole range of Cataclysm spells to cast, unleashing untold devastation on the enemy. Arcane Fulcrums burst from the ground, not only acting as loci for the swirling energies that pervade a battle fought amidst the Storm of Magic, but changing the way a Warhammer tabletop looks and interacts with your armies.
