Appears that the Ancient Smoldering Behemouth …one of 5 possible spawns at the end of The Forlorn Spire quest chain in the Molten Front (i.e. Cataclysm expansion area…Mount Hydal) …is no longer spawning normally. I have run the daily quest some 40 times in the past two months and he never spawns. Each of the other 4 have shown up a minimum of 5x…with the Ancient Charscale showing up over 16x. While it could be pure bad RNG luck…the odds are might poor of 0/40 spawns even with only a 20% chance on each (i.e. 0.013% chance of NOT having it spawn on any of in 40 attempts).
This is needed for the Ready for Raiding II achievement and Veteran of the Molten Front achievement.
