TERA players will definitely want to check in beginning August 15th when en Masse Entertainment debuts a brand new dynamic event called Argon Assault. Players will work to fight off daily invasions of argons during twice-daily events in several locations throughout the game. A new currency will be the reward that can then be exchanged for cosmetic items with a definite “otherworldly” feel to them as well as flying mounts, weapon skins, accessories and enchanting materials.
