Primarily requested by Puss. Yesterday (April 25th) there's a new feature to change your existing dualjob to another dualjob. To change isn't exactly the right word here, as after doing this quest, you can switch between dualjob, so it's more or less "adding a new dualjob" to your char.
This picture have nothing to do with actual content
Before you begin you need to have finished some quest first. You need to have finished the dualjob book quest (the one that needs you to collect 3 moonstone, 3 yellow tablet, and 3 power cylinder). After you finished the prerequisite you will now eligible to do this quest.
Go to talk to [フレイズ] in the uptown, she will ask you things, as always, just choose randomly till correct (I forget, but i think it's the second choice twice).
Talk to [フレイズ] again in the infinite corridor B41F. After a few cutscene, you will be asked to collect gems. These gem is similar to the one that you use for your first dualjob change. She will said that the first gem are located in the B135F of hellish corridor, so make your way to that place.
You need to go to 135th floor. As prerequisite, you need to start from 125th floor portal so you must start your way from 100th floor, or if you have friend, you can start from 125th floor. Do not start immediately from 135th floor because it'll regarded as invalid (I made this mistake). After reaching the floor, talk to the guard near the stairs. After conversation, you will get your first jewel, the red one.
Go back to B41F, talk to [フレイズ] again. After conversation, she will offer you 6 choice, which basically you asking where the other jewel is.
We will look for green jewel now. For this jewel, you need to prepare 3000 abyss matter. Go to Hellish IC lobby and look for [ギルダーツ]. He will offer you stuff for 3000 Abyss matter. Buy it, and you will get a coffin.
After you get the coffin, talk to the gladiator npc which in charge to open golden pururu chest. After that you will get the green jewel.
For the blue one, you need to talk to force master npc in B41F, no prerequisite for this one, just talk to her.
For the last one, the yellow jewel, you need to finish clumsy merchant quest. It's a quest where you need to give a merchant [ドジな商人] which stuck inside jail. He appears on B43F, B58F, and then B67F consecutively. Prepare 4 Rusty key to do this quest. In second jail, you need to enter the jail yourself to talk to him, other than that, you can talk to him from outside the jail.
After you finished the clumsy merchant quest, talk to him again in the B41F.
After you collect all 4 gems, talk to [フレイズ] again and then talk to the lobby receptionist guards, then go back to [フレイズ]. She will then offer you a quest to combine the jewel by fighting against HIC boss, Nyarlathotep.
After you kill her, talk back to [フレイズ] and then you can choose your next dualjob. The level will be reset but you can revert back to your first dualjob anytime you want. You basically now have access to 2 dualjob. You can add more dualjob but you need to do the quest again, which gradually will become harder and harder, for your third dualjob change, you need to reach 205th floor and I think the boss is also buffed more.
That's all, I have been on hiatus for a long time so my skill are pretty much rusted over the time :( Special Thanks to:
Yeah, I'm just freeloader *shot*
