Cast powerful magic: Call a meteor strike, invoke a powerful blackhole and protect your towers with powerful arcane shields.

Build a magnificent Castle: Use wood, stone and metal rooms, to build solid ramparts and impressive towers

Mix all of those elements to build your very own Castle, from a magic tower casting huge spells, a soldier swarm on the walls of your opponent, or a rolling thunder of spikes and stones crushing its ramparts.
