Requirements

  • 1 Contaminated Crystal from Dark Cloud Mansion
  • 3 Red Corals from Eva's Gift Boxes
  • At least 10 Fire Potions from NPC in town
  • Stocked up on shots, ores, potions, elixirs, recovery scrolls, resurrection scrolls, symbols, holy cups, etc.
  • 90 minutes of your undivided attention.

Intro

Steam Corridor is one of the 3 instances from Crystal Caverns.
A minimum of 3 Red Corals is required, but the more the better since they're tradable. In addition to the instance's 90 minutes, each party member has a time limit: your buff bar shows your remaining time. Once the event timer buff expires, it will consume a Red Coral, giving you more time. You'll be teleported out if you don't have any Red Corals.

The Contaminated Crystal will be consumed if you kill the instance Raid Boss. The Refresh Timer will begin when the Raid Boss dies. To reenter Crystal Caverns, repeat Dark Cloud Mansion and wait 24 hours.

Players who stay dead for more than 10 minutes or disconnect from the instance will be ported out.

Farming instance monsters

If you only wish to farm the instance monsters, you can skip the Raid Boss.
To reset the instance: skip the Raid Boss and leave the instance with a Scroll of Escape or Party Return and wait 20 minutes for the timer to reset. You can then enter the Crystal Caverns again. Don't drown while you wait!

Entering Steam Corridor

You can access the Crystal Caverns through the Oracle Guide beneath Parnassus. In order to enter, you need at least two players in your party, and everyone must have a Contaminated Crystal. Once you click Touch the Sphere, the 90-minute timer starts, and you're teleported to the Preparation Room (Marked as Red Triangle on the map).

In the Preparation Room, speak with the Oracle Guide and select Steam Corridor and go through the left door.
You will arrive in a middle of a long corridor with doors on either end.
Clear the monsters on the right side in the Red Coral Key Corridor until you get to Gatekeeper Provo. Kill Provo and get the Red Coral Key. Use the key to open Corridor Door and start Steam Corridor instance.

Steam Corridor Walkthrough

Steam Corridor MapThere are four rooms you must progress through before you reach the raid boss Kechi. You must clear the room completely before you can move to the next room. This includes killing all of Kechi’s Minions and Fire Traps.

Since there is no path between rooms, if a member of your party disconnects or gets ported out at the second room or later, he/she cannot rejoin. At this point, just reset the instance. SOE or PR and wait 20 minutes before you reenter.

All monsters have fire resist, they are social and work in groups. Most monsters do AOE or single target fire nukes which hit very hard even with full fire resist.

  • Bring Fire Potions, use Song of Flame Guard and Song of Warding.
  • Do NOT use any Mass Cubic as they tend to trigger when you put a monster to sleep.
  • Make sure your party setup can crowd control the monsters, – trance, silence, root, fear.
  • Use a dagger on Silent Move to lure a group at a time, and to detect and deactivate Fire Traps that stand in your path.
  • The Sword Muse or Tank aggro mobs one by one, in no particular order, as the damage dealers assist.
  • Once the room is cleared, four Eva’s Protector appear.
  • You need to heal the correct one until the Oracle Guide spawns and allows you to teleport to the next room.

The correct order is always 2-4-3, so you heal the 2nd Eva's Protector in the first room, the 4th Eva's Protector in the second room, and the 3rd Eva's Protector in the third room. A Red Coral is consumed when you port from the 2nd to the 3rd room.

If you need to regenerate mana at the end of clearing a room, heal Eva’s Protector until Oracle Guide appears, do Shadow Dance and Song of Meditation and teleport to next room. Do not wait inside the room you just cleared. Both Eva’s Protector and Oracle Guide will disappear after a while, and you will be stuck – reset the instance if this happens.

Once you have cleared the fourth and last room, a door will open leading you to Kechi’s Room.

Kechi

Kechi is one of three raid bosses you will have to kill to be able to enter Baylor’s Lair. Your Contaminated Crystal will become a Red Crystal when Kechi dies, and you will receive a Black or White Seed of Evil – Shard.

  1. Wait for the whole party to enter before you start the Raid Boss. When you hit Kechi, the door will close. This fight is pretty straight forward. Kechi doesn't deal a lot of damage and is highly resistant to fire attacks. The event timer buff remains, but it has no effect whatsoever.
  2. When Kechi is at 75% HP, a wave of Kechi’s Henchman will appear. They have high HP regeneration and do group heals, so you will have to kill them one by one. They don't do much damage individually, but if you have multiple on you, kite them so your healers don't run out of mana. After you clear the wave, continue attacking Kechi.
  3. Similarly, when Kechi is at 50% HP, another wave will appear. Repeat the same process as before. After you clear the wave, continue attacking Kechi.
  4. At 25% HP, another wave will appear. There is no point for you to stop hitting Kechi and clear this wave, it will keep respawning. Focus down Kechi while bards provoke and kite as many Kechi’s Henchman as they can.
  5. Once Kechi dies, the wave will not disappear, you have to kill all mobs.
  6. An Oracle Guide will appear where Kechi died. If every party member has 1 Red Crystal, 1 Clear Crystal and 1 Blue Crystal you can challenge Baylor.

If anyone in party disconnects or stays dead for more than 10 minutes, they will get ported out and cannot reach Kechi’s Room nor do they enter Baylor’s Lair if party leader selects that option. When Kechi dies, they will not earn a Red Crystal, nor will they consume a Contaminated Crystal.
