Tera will be closing out January with a hefty update to the game. On January 30th, Guardian Legion will go live.
Guardian Legion is a group of elite soldiers ready to take on the Red Raiders. When the update goes live, six new Guardian Legion missions will pop up all over the map and be available to groups of 15 max-level players. Earn additional rewards from these missions by being an active subscriber to Tera. For each mission completed, you earn Guardian Legions points, which case be exchanged for boxes that contain gems, credits, upgrade materials, and Item XP.
