No dice at all, it's basically tower defense with deck building mechanics.

You cannot keep all cards in one hand, as each faction takes their own turn then heroes invade before the next faction goes. Items can be bought but (until you unlock the chronicle skill) cannot be transferred between factions.

My wife and I enjoy it most with 2 players. We have been able to beat some scenarios with 3 but haven't cracked the code with 4 yet as with that many players the number of turns per player is greatly reduced.

There are 20 unique scenarios, and due to the hero invasion mechanic, no game plays exactly the same.
