The quest given to you by Harith within the Abyssea - Attohwa area in which you synthesize a "Phial of Miasmal Counteragent," and trade it to a "Dark Miasma" that can appear in several locations of the area is EXTREMELY luck based. Are there any plans to adjust this and perhaps make it less luck based? Personally, I have spent somewhere in the ballpark of 15-20 Traverser Stones on and off attempting to locate the "Dark Miasma"
