Glitching 1-Man Room For Celestial Arena
All credit for this goes to Missing He, I'm just explaining it since many people were confused by his guide. I'll post exactly what I did, step for step, to ensure it works for all.
1) Have both accounts join celestialarena-XXXX (I always use /join celestialarena-2000, this step might not be required)
2.1) Have the account you want to farm with join the room in question with /join celestialareanb/c/d-2000. If you're not sure how to cell jump to find the boss you want, go to Step 2.2.
2.2)To find the coordinates for the specific boss you want, (In Le Bot at least), first join the boss the normal way, open up "Bot Manager" and click the small grey square next to the words "Move to cell". The coordinates that come up to the left are that bosses coordinates. (For Aranx, it's Cell: r10, Pad: Left) Do /join celestialarenab/c/d-2000. With those coordinates saved, click "Move to Cell" to add those coordinates to the bot manager and then, enable it!
Viola, you are now in the place you need to be.
3. With your 2nd account, do /join celestialarenab/c/d--2000, it doesn't matter if the account hasn't unlocked the other levels. Do this 5 - 9 times, ensuring the "Room full" message pops up each time
4. It is done. The room is now glitched and your player inside the room is free to farm away until they leave, in which case you simply repeat the above steps. Happy Lumin Badge hunting!
