Central Laboratory

A story run for Lv135+ parties in the Verus laboratory: set a binary door code, watch a doomed particle experiment, and kill three random boss monsters it drags in from another dimension. Once a day.

Memorial dungeon
The experiment goes wrong on cue. You are there to clean up what climbs out.
In the Verus laboratory a team of researchers is about to run a huge particle accelerator under the eye of a Mother Computer called MA-4885. You travel back in time to watch. Most of the run is a staged scene. What you actually fight are three random boss monsters that the broken experiment pulls in from a "demi-plane", one after the other.
The Civilization Explorer also warns in red text that taming monsters will hold up this dungeon. Each round only moves on when its creature dies, so a tamed one blocks the run.

How to go

  1. Be level 135 or higher and in a party. Under 135 the Explorer tells you to come back near level 135. Without a party he and the Dimension-mover both ask you to form one first.
  2. Talk to the Civilization Explorer. The first time, he tells a short story and asks you to look around the ancient laboratory. Pick Ok at the end. This sets and then completes the quest Strange Ancient Science.
  3. The leader picks "Produce a crack of time". Other members are told to bring their leader. If the crack cannot be made, the Explorer shows the party name and "Unknown Error".
  4. Everyone steps into the Temporary Dimension-mover. A map announcement says which party is entering. You land at (120, 30) inside. If the leader has not made the crack yet, the Dimension-mover says the passage has not been vitalized.
Entering sets Trace of Laboratory Access, which lasts until 04:00 server time. While it is on, both NPCs refuse to send you back ("There are remaining traces of the last event"). Talk to either once the time has passed and the trace is erased.

Inside

The door code

The Probationary researcher at (104, 34) is the first gate. Only the party leader can talk to him. He asks if you are here for research project 32001, and picks Yes. After about 9 seconds of lines he says you may come in. This opens the side warps along the corridor, eight switches, a main switch, and a Senior researcher. The door cannot be opened from the other side.
  1. Talk to the Senior researcher at (45, 32). He tells you today's access code as a number. It is (month + day of the month) x 5 on the server date. On 11 October that is (10 + 11) x 5 = 105.
  2. Write it in binary. 105 is 01101001. The eight switches at (37 to 52, 37) are bits 1 to 8, from left to right. A switch set ON is a 1, OFF is a 0. Talk to each switch and choose ON or OFF.
  3. Press the Main Switch at (34, 37). It prints the code, the code you entered, and after 6 seconds either "The code is correct. Opening door." or "The code is incorrect. Please try again."
On the correct code, two warps open at (29, 38) and (48, 82), and four doctors appear in the experiment room: Silvia, Federico, Artemia and Vincent. The eight switches disappear.

The experiment

Walk into the experiment room around (80, 89). A scene begins: researchers talk, Dr. Fresa's voice reports the time over the speakers, a particle accelerator heats up, and MA-4885 announces an "unidentified creature" with a 5-second countdown. Then one random boss monster appears at (90, 88). Kill it and the next round starts.

Round 3 can bring in
Ifrit
(about 6.9 million HP) or
Detardeurus
(about 6 million HP). The announcements between rounds say the creature "has no interest in us" and that the computer is trying to line up the two dimensions.

The finale

After the third boss, the final scene plays for about 1 minute 35. MA-4885 starts the dimension move. The four doctors blow up one by one, and the lab announces "Dimension move 100% completed". About 15 seconds later a gateway opens at (123, 88) and warps you out to the Verus field at (152, 150).

Rewards

Nothing is paid by the laboratory itself. The loot is whatever the three random monsters drop, with their normal rates. The doctors and the Senior researcher give nothing.

Notes

  • The doctors' lines and the countdowns are only staging, but they set the pace: the monsters appear exactly when the scene ends, not before.
  • The number follows the server date, so everyone who opens the door on the same day gets the same one.
  • The weighted lists give each MVP 7 chances in 105 (or 98 in round 2) and each mini-boss 2.
  • The Explorer's "party of 1 or more" means you can run it alone as a one-person party.
