Spellrift Legends | Prototype Unboxing

About Spellrift Legends, from BoardGameGeek:

The Void has awakened, tearing open rifts between distant worlds they now seeks to devour. To stop them, the greatest legends of each realm gathered. Spell Rift is a cooperative deck building adventure game where iconic heroes clash against the Void. Build your deck, explore the different worlds, seal Voidrifts, and forge your legend before your world too is consumed. Players select heroes with unique attributes and join together to defeat the final Boss. Players can choose a single adventure or use the campaign mode with 9 bosses to defeat. Players win the game by completing the Boss's unique objective, and then summoning and defeating the Boss in a climactic battle. But there are multiple ways our heroes can lose as well. -description from the publisher
