The game's enchanting mechanics will also be simplified, and a new quest UI will "streamline 60 to 65 leveling, allowing players to teleport right to the action, find groups, or turn in quests from any location."
Finally, you'll want to log into TERA prior to December 16th and pick up your free Northern Initiative Pack. It includes rare potions, campfires, buff charms, a white tiger mount, and more. TERA's Fate of Arun expansion will be a free content update via Steam and the game's official website.
