From the release:
Enter the world of witches, warlocks, and demons in Wizkids’ newest release Approaching Dawn: The Witching Hour, designed by Ken Shannon. Cast spells, summon familiars, and work together to survive the night as your personal Demons manifest in an attempt to steal your magic powers… and soul!
Cast two different types of magic: Black and White. Devastating Black Magic spells are used to defeat enemies in front of you, but be careful, Black Magic has its costs, and will hurt other members of the Coven. Conversely, White Magic heals you and can be used to help out a fellow Coven member. Use both to banish creatures that enter our world back into the Void!
It’s not just monsters the Coven needs to worry about. As a Witch’s soul darkens with the use of magic, they will gain Corruption. If a single Witch earns 20 or more Corruption before the end of the night, the Coven falls and everyone loses. If all survive until dawn, then the Coven wins!
