How to get in
Talk to the Cavern Guide in Twin City (288,357). Entry is free, with no level or item check. He sends you to your deepest unlocked floor; you can't pick a floor.
- At level 50 you get a
Cavern Exorcism Invitation when you log in. Reading it gives 30 Study points and walks you to the Guide. - Entry is closed from 00:00 to 00:08. From 00:00 to 00:05 everyone in the Cavern is sent back to Twin City.
- A Floor Defender on each floor takes you back to Twin City.
PK in the Cavern
All six floors are normal PK maps, not free-PK zones.
- Hitting a white-name player turns you blue.
- A kill gives 10 PK points: 5 if the victim is on your enemy list, 3 if their guild is your guild's enemy.
- You turn red at 30 PK points and black at 100.
- A black name goes to jail on death.
- PK points raise your chance to drop items when you die.
Going down a floor
Land the killing blow on Star Devils of your floor. Any devil counts, repeats too. When your count is reached and your Battle Power is high enough, that kill moves you one floor down.
| Step | Star Devil kills | Battle Power |
|---|---|---|
| 1F → 2F | 6 | 165 |
| 2F → 3F | 6 | 250 |
| 3F → 4F | 6 | 300 |
| 4F → 5F | 5 | 330 |
| 5F → 6F | 5 | 360 |
- On the step kill, the devil's loot goes straight into your bag, with the floor's Slayer Pack (
Cavern 1F Slayer Pack to 
Cavern 5F Slayer Pack). The pack holds that floor's fixed items and silver. - Below the Battle Power, a message names the value you need. The devil drops normally and you stay.
- A floor's counter resets 7 days after your last devil kill there. Keep killing on your floors, or the Guide sends you to a higher one.
- The "Devils of Cavern" quests only show the six spawn points. They give no reward.
Star Devils
Only Star Devil A and B spawn. Each listed minute of the hour, a floor below its limit spawns one, A or B at random, at one of its six points. Every spawn is announced to the players on that floor.
| Floor | Monster level | Star Devil life | Spawns | Alive at most | Silver per devil (10 piles) |
|---|---|---|---|---|---|
| 1F | 50 | 50,000 | about every 2.5 min | 24 | 15,000 |
| 2F | 70 | 100,000 | every 3 min | 20 | 60,000 |
| 3F | 100 | 500,000 | every 3 min | 20 | 120,000 |
| 4F | 120 | 5,000,000 | :00, :15, :30, :45 | 4 | 500,000 |
| 5F | 130 | 15,000,000 (boss) | :00, :30 | 2 | 1,000,000 |
| 6F | 140 | 30,000,000 (boss) | :00 | 1 | 3,000,000 |
- 1F-4F devils are big monsters. 5F and 6F devils are bosses.
- The ordinary monsters (DarkGhost, NightVampire, UnderworldShadow and their kin) drop potions and roll the normal hunting table. Star Devils don't.

Tips
- Land the killing blow yourself: damage from friends doesn't count.
- Raise your Battle Power before your last kill on a floor, so the step kill takes you down.
- Watch the floor announcements: they name each devil and its spot.
- 5F and 6F devils are bosses with 15 and 30 million life, so bring a team.
- Other boss times are in Boss islands.
