Journal

The House Manderville artisan stands ready to facilitate your augmentation request.

※Changing classes or jobs will prevent progress during this quest.

You approach the House Manderville artisan to request the perfection of another Manderville weapon. The ever-enthusiastic craftsman assures you that all is in readiness─except, of course, for the three ample samples of crystallite he bids you prepare.

※You may not proceed with a class or job that is different from when you accepted this quest.

※Chunks of cosmic crystallite can be obtained from Jubrunnah at the aetheryte plaza in Radz–at–Han.

With your proffered crystallite in hand, the House Manderville artisan calls upon his High Crucible colleagues to assist with the weaponry's final stage of refinement. The result is “bloody immaculate,” as Gerolt himself puts it, and you are encouraged to return (with more crystallite) should you wish to enhance another Mandervillian masterpiece.

Dialogue

House Manderville Artisan: Might I assume you're here to perfect another weapon? Everything is in readiness...except for the incredibly rare and difficult to acquire meteoritic material, of course.
House Manderville Artisan: If you would be so kind as to provide three ample samples of crystallite, then we can proceed with the augmentation of your chosen armament.

System: Chunks of cosmic crystallite can be obtained from Jubrunnah at the aetheryte plaza in Radz-at-Han.

Delivering the cosmic crystallite:

House Manderville Artisan: Are we all set to proceed, Master Surname?
House Manderville Artisan: Splendid, splendid. I shall gather our High Crucible dance troupe to extract the essence, then have Master Gerolt elevate your weaponry to the pinnacle of smithing perfection!

House Manderville Artisan: Now for the coating of Ultramanderville.
House Manderville Artisan: As before, we shall finalize the oil's composition based upon your stated preferences. The weight given 
to each martial quality is entirely yours to decide...
House Manderville Artisan: As you wish, Master Surname.

Gerolt: And done. Bloody immaculate craftsmanship, if I do say so meself...
Gerolt: Bear yer new [Mandervillous weapon] with pride!
House Manderville Artisan: Another masterpiece of Manderville weaponry taken to its highest, finest form. The sense of achievement is incomparable!
Gerolt: Aye, especially since the achievement was mostly mine. Well...I s'pose you two have shown some improvement.
House Manderville Artisan: Y-You think so, Master Gerolt? O joyous day!
Gerolt: Bloody hells, do ye have to do that now?
House Manderville Artisan: While originally conceived to extract crystallite's aetherial energies, the Manderville dance has since come to serve another noble purpose: the unabashed expression of pure elation!
House Manderville Alchemist: Join us, Master Gerolt! You know you want to!
Gerolt: Balls to that! Ye can bugger off with yer fancy fop-fashioned fellowship, an' all!
House Manderville Artisan: Wield your charges well, Master Surname, and do let us know if you've more pieces in your armory you wish to perfect.
House Manderville Artisan: We shall be waiting with open arms...to accept the necessary offering of crystallite, ahaha.
House Manderville Alchemist: Likewise, I shall gladly adjust your weaponry's properties should you find their aetherial balance lacking. We are your humble servants!
