Gemino is an Atlantean myth technology in Age of Mythology: The Titans that is available to worshipers of Hyperion and can be researched at the Temple. Once researched, it doubles the amount of javelins throws by Satyrs with their special attack (six instead of three).
Mythology[]
“ | Satyrs were not warriors or soldiers, though they fought fiercely when threatened, deprived of wine, sleep or nymphs. They rode timid donkeys into battle and carried javelins crafted for them by dryads. The eldest Satyr, Silenus, could throw two javelins at a time and from time to time would teach other satyrs the trick of it. | ” |
