Chaostle

From BoardGameGeek:

Chaostle (kâ'os'l) is a combination of the words Chaos and Castle. Chaostle is a three-dimensional castle fantasy board game. Each player selects their starting armies that they will use to battle against their enemies in an attempt to conquer the castle for their King or Queen. The armies consist of many different fantasy fighters with unique skills and weaknesses such as wizards, dragons, unicorns, knights, archers, etc. The fighters are custom collectible plastic miniatures. The game has many levels of strategy that can be offset by a wide range of fates (both good and bad).
