Started this quest pre-merger, killed 3 myloc lifetakers, then there was the merger... a week ago our group hunted exactly the same place where the lifetakers had been pre-merger and managed to find one (even pre-merger there seemed to be 3 spawns with one lifetaker + necroflies per spawn, thoroughly scattered all over the long road to the fortress), after killing the one we nearly lost our hopes of finding another one, but after nearly killing one we got TWO adds... did some jogging [H] and killed them.

Oh, and btw we were group of three adv 35,40,60.
