You must place your hero by the major god statue in each castle to capture it. After you have done this you can buy the units in the castle. The more castles you own the faster you will get gold. You must Capture all castles to win the game.
The idea for this map came from Demigodseers Age of Castles V3 which I loved so much I had to make my own version :)
Also this is my first map I have made I hope you enjoy it!
UPDATE:Hero regen added, as well as some new units and a Cinematic, can buy another hero as well
