The Temple of Battles allows you as a God to fight against others Gods on several different maps. Since the release of v2.0 the Temple of Battles has disappeared from the game.
It worked along the same lines as the Mount of the Gods with the same maps as well as the various winning criteria for each map, all of which can be custom made for each game.
Winning a match would provide the player with Resource Cards which would work towards unlocking more Technology Cards.
