What is Bifrost?

The game's description is short: defeat enemies in the PvP zone and kill the monsters in Bifrost. When the timer runs out, the Bifrost Assault begins in the middle of the Colony Zone, that is Ronark Land. You pass into Bifrost through the [Bifrost Monument] in the central part of Ronark Land.

Inside there are connected sections: Ego, Lava road (no teleport), Glutton, Resting Area, Wrath, Room of the Pursuer, Sloth, Room of Maze (gas area), Long Corridor, Lust, Envy, Greed, Lost Room and a safe zone for each nation.

How do you get into Bifrost?

  1. Cross into Ronark Land: the gate takes level 70 and above and costs 17,000 Noah.
  2. Join the Bifrost Assault in the middle of Ronark Land when it opens. Bifrost only opens once one nation beats the other.
  3. The winning nation goes in right away; 30 minutes later both nations can enter. With no winner, neither side can enter.
  4. You pass in through the [Bifrost Monument] in the middle of Ronark Land. Entry costs 2,000,000 Noah; without it you cannot go in.

What are Dark Fragments for?
