About the game
You make a character from one of five races, start as a novice and later pick a class: Fighter, Mystic or Bandit. Then you take quests, clear dungeons, fight bosses and collect better gear. It plays a lot like an old online RPG. Combat is quick, with a dash, a timed block and a handful of skills you choose yourself.
You can play alone with no internet, or host a lobby through Steam and let friends join. Lobbies come in different types, such as PvE, PvP, social and role-play. In a party of up to six, you share quests and take on dungeons together. Your character is saved on your PC, so the same one works in solo and online play.
The game is still in early access and runs on Windows only. It suits friends who enjoy leveling characters together over time.
