Tera is currently running the Forgeheart event, meant to gear up players. The event will run until April 7th, so now is a good time to log into Tera and gear up.
Starting Tuesday, March 17 (10 a.m. Pacific) and continuing until Tuesday, April 7, log in every day to receive a special item, then complete dungeons to earn the Forgeheart Letters T, E, R, and A. Combine all four letters into a Forgeheart Letter Key, and you can unlock Forgeheart Jackpot boxes containing Annihilation or Dark Light Weapons suitable for your class. During week one of the event (March 17 – 23), your daily login will net you an Infinity Coin that cancels the Adventure Coin cost of any dungeons you enter for the next hour.
More info about the event can be found here.
