What is Bifrost in Knight Online?
Bifrost is a separate map you enter through a gate in the center of Ronark Land. Each nation has its own safe zone, and the rooms in between are named after the sins: Ego, Glutton, Wrath, Sloth, Lust, Envy and Greed. Along the way there's the Lava road (no teleporting), the Room of Maze gas area, the Room of the Pursuer, a Long Corridor, two resting areas and the Lost Room at the end.
The map's boss is Ultima. NTTGame's September 17, 2026 notice introduces Ultima's Dungeon as "the lair of Ultima that has invaded the Bifrost map", and stages 16–20 of Full Moon Rift are the Bifrost Army. Which Bifrost content is open on which server is a separate topic, covered in USKO Krowaz, Bifrost and Eslant: server differences.
How do you enter Bifrost?
The game's own help text and the system messages in Ronark Land describe it like this:
- The Bifrost Monument stands in the middle of Ronark Land (522, 550). Normally it can't be attacked.
- When "Bifrost Assault is now taking place in the middle of Colony Zone." shows up, the siege is on; per the help text it lasts 30 minutes.
- The nation that takes the monument enters through the Bifrost gate and has the first hour to itself, safe from attacks.
- After that hour both nations can enter and PK starts. Per the help text, entry stays open for 2 hours; the countdown reads "When the remaining time has expired, the gate to Bifrost will close." When it runs out, everyone is sent back to their nation's town in Ronark Land.
- If nobody takes the monument within 30 minutes, the gate doesn't open that round and you wait for the next siege.
These timings come from the game's help text; NTTGame hasn't repeated them in a recent notice, so the server may be tuned differently. The Bifrost Assault message in Ronark Land is the real signal.
Thinking of going in with someone on the same connection? Since the August 25, 2022 update on the Turkish servers (USKO), UTC and Bifrost can't be entered from the same IP. Since October 6, 2022, a DC or logout on the Bifrost map puts you back in the Ronark Land safe zone.
What time is Bifrost?
Bifrost runs daily at 21:00 and 02:00 Turkish time (USKO). Those times come from the in-game event calendar; NTTGame hasn't announced them separately. Watch for the siege message in Ronark Land; the times can shift by an hour when daylight saving changes.
Bifrost PK rules and EXP loss
- The Bifrost entrance is neutral for both nations; outside the safe zone anyone can attack.
- Dying to the enemy nation costs you 0.5% EXP.
- There's no cross-nation chat inside and names are hidden: El Morad players show up as [Conquerer of the Continent], Karus players as [Great Hero].
- [Gatekeeper of Lost Chamber] Rothen manages the Lost Chamber gate. Per the help text, all seven sin pieces together act as the key to the last lost chamber.
Bifrost monsters and their special skills

Do Bifrost monsters spawn in Ronark Land?
On some servers, yes. On February 7, 2019 NTTGame added Bifrost monsters to Ronark Land and Ardream on the new servers of that time, and on May 6, 2021 it lowered their drop rates in Ronark Land. The March 23, 2023 notice then announced Envy, Greed, Sloth and Lust for the Ronark Land maps of Agartha, Pandora, Felis and Zero with the April 20, 2023 maintenance.

What do you get from fragments at the Chaotic Generator?
The Chaotic Generator sits to the right of Moradon's East Gate (857, 785) and turns each fragment into one random item. Going by the game's exchange list, the odds climb with the sins: Pride's fragment mostly gives BUS and enchant scrolls, while Greed's has the best unique chance.
| Sin | Regular fragment | Unique weapon/accessory | +1 weapon/armor | Nightmare Crystal | Holy Knight material from the Dark fragment |
|---|---|---|---|---|---|
| Pride | Fragment of Arrogance | 0.39% | 16.9% | 20% | 13.05% |
| Gluttony | Fragment of Gluttony | 0.65% | 25% | 25% | 15.05% |
| Wrath | Fragment of Rage | 1.95% | 48.8% | 30.19% | 17.1% |
| Sloth | Fragment of Sloth | 3.25% | 59.04% | 35.19% | 19.1% |
| Lust | Fragment of Lechery | 6.5% | 51.45% | 40.29% | 21.15% |
| Envy | Fragment of Jealousy | 9.75% | 43.25% | 45.49% | 23.15% |
| Greed | Fragment of Avarice | 13% | 35.3% | 50.99% | 25.2% |
The unique pool is Sherion, Lugias, Avedon, Helenid Cross Bow, Hell Blood, Garp, Elysium, Holy Animor, Syphioric, Flame Ring, Shio Tears, Imir Ring and Foverin. Fragment of Avarice has a 13% unique chance. A Gold Bar is 1 in 10,000 on most fragments.
How do you craft Holy Knight and Dark Knight armor?
[Disciple of Hepa] Shozin in Moradon (705, 578) makes the armor. Every piece takes a mold, a Light Elemental Stone and your class recipe. Sundries sells the molds, and the Light Elemental Stone comes from Shozin's daily quest.
| Piece | Mold | Holy Knight | Dark Knight |
|---|---|---|---|
| Pauldron / Robe | Ancient Armor Mold (Top) | Metal Plate x1 + Fusion Stone x3 | Ancient Sheet Metal x1 + Transmutation Stone x3 |
| Pads / Pants | Ancient Armor Mold (Bottom) | Metal Plate x1 + Fusion Stone x3 | Ancient Sheet Metal x1 + Transmutation Stone x3 |
| Helmet | Ancient Armor Mold (Helm) | Metal Plate x1 + Fusion Stone x2 | Ancient Sheet Metal x1 + Transmutation Stone x2 |
| Gauntlets | Ancient Armor Mold (Gauntlets) | Metal Plate x1 + Fusion Stone x1 | Ancient Sheet Metal x1 + Transmutation Stone x1 |
| Boots | Ancient Armor Mold (Boots) | Metal Plate x1 + Fusion Stone x1 | Ancient Sheet Metal x1 + Transmutation Stone x1 |
For Holy Knight the plate and Fusion Stone depend on class: Warrior Tempered, Rogue Moonlight, Mage Magic, Priest Solar, Kurian Chaotic. A full Holy Knight set needs 10 Fusion Stones, 5 Metal Plates, 5 Light Elemental Stones and 5 recipes.
