I was hunting in HoH, farming TS items with my chanter, when I clicked through to HoH -B and found both the Fabled LMM standing - flanked on both sides w/ his Honorable Protectors - and the normal Lord Mith Marr, standing right next to him!
I never realized both mobs could spawn together at same time, but sure enough they did. So I ran my level 110 Druid over and the two toons w/ level 106 chanter pet downed them both together. This was last night on the AB server. I can't remember the last time I had this much fun in EQ!! Was surprised to see Fabled LMM was still a green con to level 110 toon.
Even at lvl 106, chanter slows after tash still wouldn't land - Fabled LMM is highly magic-resistant, but the chanty pet and 110 druid fire-cold DoTs/nukes took care of them both pretty easily. A bit overkill. Fabled version dropped two "Fabled Blade of the Tempest" items, the haste belt, the Fabled Cloak of the Wrulons and quite a few spectral parchments. I assume because I killed both the Fabled and non-fabled versions - I had two "Planar Projections" spawn, hailed one, so was added perk getting the PoP flags too.
Note if you decide to run low-level friends over to grab some of the loots, the gargoyle-cat guards on the podium next to LMM's spawn point respawn pretty quickly over and over.
Have fun!
