I've done the entire Kerra line of quests twice. Was wondering
if anyone did them anymore because last week while passing thru
kobold cave to SBM I saw Krrgar the Defiler up. WTF lol took me a few days of kiling his PH before he spawned for me last year.
Yevran Ty'Rizeth spawned for me once in 5 hours, and the other
time in 8 hours. I watched a movie, did some laundry, and cooked dinner while keeping the other mobs corpses refreshed and waiting for Yevran's PH or Yevran himself to spawn.
I had the worst luck with the harpy queen in Kerra 59 quest,
I'd kill her place holder (slower respawn time than the harpy
next to it) many times, but finally lose patience and log off, but repeat killing the PH and its neighboring harpy a few more days until she spawned.
The starshimmer bracers for tanks and helm for casters
from Kerra 59 are decent.
