Here is a post I found and personally used to level solo in Kaesora from 44 - 48.
I hope this helps.
Guide: Soloing Church area in Kaesora
Levels: 44 +
Experience: 1% - 3% per kill up to level 47
Description:
Following this guide, you will be able to solo the church area in Kaesora and get awesome experience. I was getting 1% to 3% per kill as an Iksar (20% exp penalty).
Spell line-up:
1) Drain Spirit
2) <any>
3) Rest the Dead
4) Call of Bones
5) Feign Death
6) Augment Death
7) Shackle of Spirit
8) Hungry Earth
Step I – Getting there
Head to Field of Bone and zone into Kaesora. Have DMF and Gather Shadows up. Run straight ahead and go down pit to the next level and run straight. Go down the hole in the floor and make a u-turn. Continue down the passage way till you get to a 4-way split. Go straight. Right around the next corner you will stop there and wait for any roamers to leave the area. Bring up IVU. And continue on to the left. Keep to the left all the way down to the church area. Go past the entrance to the church back into the little corner / cubby-hole area. This is where you will set up camp (+50, +500). Park your pet at (-10, +480).
MOBS
Step II – Single Pull
Have pet Augmented. Using the camera angle mode <F9> and camera pan up / down <ALT-Page up / Page down>, target and cast Rest the Dead on all the mobs indicated in red. This has never been resisted for me and seems to always work as of 12/10/2002. Pull in the order indicated with the numbers. Use Shackle of Spirit to pull!!!
Step III – Killing
When all the mobs have been Lulled and you pull, /pet attack right when the mob is on top of pet. If it is a ghost type mob make sure you keep it rooted as it will run when low on life. (I use hungry earth to root as it aslo does dmg to the mob). If it is a skeleton mob your pet is killing, there is no need to root as they will not run when low on life. I use a life-tap to do over 1 dmg and get max experience.
The trick here is to just pull with Shackle of Spirit and keep pet Augmented. It’s a really easy fight for the pet and you have to almost do nothing except keeping the ghost mobs from running, and doing at least 1 dmg to get full exp. After you kill #5 on the map you can move to the dried up pool thingy (in between #3 and #4) I didn’t go behind the pool and the ghost there didn’t agro. I go to this spot to make tageting mobs 6 – 9 easier (for Rest the Dead) then go back to pull spot to pull. There are mobs below #’s 6 - 9 (in a pit) that didn’t agro at all when I was here.
Step IV – No No’s
Do not pull any of the mobs in blue. By the time you kill all 8 or 9 mobs that are up the first one will be re-poping soon. This gives you enough time to med and re-Augment pet. You only have to cast Rest the Dead on the red mobs indicated. No wonderers or extra agro will occur if you pull this way.
Step V – Xolgoz
Occasionally you will have Xolgoz spawn in spot 6, 8 or 9. Do not attempt him till you are level 46+ He is mean and resists a lot. He’s a necro (doesn't cast pet that I've seen) I believe and nukes for a bunch. Pet usually died when I soloed him at 46 and I barely lived. At 47 it’s a bit easier. Until your 46 just Rest the Dead him and leave him alone.
Disclaimer!!!
I started here at 45 – 46. I do not know how hard this is at level 44, but when I was here, the level 44 pet doesn’t even break a sweat killing these things, as long as they are slowed. Have fun and happy fear staff hunting!
