TERA is soon to be invaded by Argons. Fortunately for those living on Arborea, the invasion has a set timeframe and will really only last for about 3 weeks, from August 15th until September 5th. During this time, the Argons will be pillaging the heck out of open-world zones, and players must stand up and do something.
The Argons are targeting high-level zones and will be hitting them roughly twice a day. Only max level players really stand a chance, but those lower leveled ones out there can certainly try to contribute however they might. To help along these low-leveled adventurers, En Masse is granting double experience for all monsters killed, and they’ll also be granted nifty rewards when hitting certain levels.
