I did the faction work as a Gnome Bertox necro on Yelinak TLP, August 2022. I began as KoS It wasn't too horrible.
Iksar Bandit cave in Warsilisk Woods was my favorite spot. Some mobs on about a 5min repop, the rest on about 12min. Keep the bandit cave clear for about 12 hours, and you should reach Kindly. At kindly you can do the an iksar hermit's quest dialogue over and over again to warmly. What is odd is that this faction capped at 50 points to Ally, so it has been impossible to reach ally. You do not need Ally for skullcap quests howerver. I completed as a Gnome at Warmly.
Another tip is to get together about 5,000 bone chips and turn them in to the bone chips quest Trooper to be non-kos in Cabilis. Good luck!
