Today, actually last night, 22 April, 2018, I was surprise attacked by this creature. I looted the Fabled Darkforge Gauntlets. Let’s just say..... it’s out there waiting.
After almost two weeks of Fabled critters being present, I can say that I have yet to see Fabled Zarchoomi. I have fought Fabled Corflunk over a dozen times, but Zarchoomi not at all. I've tracked extensively in Butcherblock Mountains and have concluded that Fabled Zarchoomi doesn't exist for the 6th anniversary of EQ. I even sent in a bug report to SOE about her, but she has still not made an appearance. I can only conclude that she is bugged or has been taken out of EQ for the duration of the anniversary period. Hopefully she will return in her standard form after the anniversary is completed, I still need to collect her head until I have the Bloodforge Armor boots and greaves.
Finally saw Fabled Zarchoomi on Sunday, 4/3/2005, once on tracking, and once when she was killed as a result of my tracking. She dropped the Fabled Darkforge Gauntlets, just as Fabled Corflunk does.
