I was running my lvl 53 pally around Lower Guk and went around a corner and there was the Fabled Ghoul Cavalier, blazing red at me, lucky I had just cast inviz for undead on...
9850hps, 2079ac, full defensive AAs, Earthcaller slow'd then switching to quad lifetap weapons(150, 125, 100, 50 were the taps in blades), Entirely self buffed as a 70 ranger, and the Cav went down like a chump.
The Fabled mobs were all part of Sony's 5-year anniversary event, which is long-since over. These mobs do NOT pop in the game anymore; anyone saying they do is either misinformed, or is trying to amuse themselves by having people run around trying to pop mobs that no longer exist. I'm posting this due to the number of other posts I have seen on various Fabled mob threads indicating that people are still trying to pop them.
He dropped the Fabled Dark Reaver 3/29/04. It took 3 tries. The first and second attempts consisted of a 65 SK (me), 65 wizzy, 65 shammy, and a 65 cleric. We got him to 34% but ran out of mana and he wiped us because of a bug that made the CH miss. The sucessful attempt was SK, 2 druids, mage, wizzy and shaman all 65. It was cake. He summons, flurries and hits for about 1000 per hit. He was easily slowed with disease. I am in a very casual guild; best equipment we have is LDoN armor.
