Hephaistos is a small expansion for Theomachie. The expansion was available only for supporters of the game on German crowdfunding platform Spieleschmiede. Hephaistos is an additional card from the Greek Mythology and has his own abilities. These abilities are unique, as well as the abilities of the other Gods. So a player controlling the Greek Mythology may choose one out of 4 Gods, instead of 1 out of 3.
