When I saw the notification of HIM spawning, my "experience farm detector" lighted up. I was in Sarleon when it happened, so after a quick trip to Marleons, I went towards Avendor to see if He spawned there. A bit past Foxtead, I found the army.
I already had experience with this battle before, so this time I came well prepared Shields up, you bastard
Taking out Eyegrim and his 47 revenants was fairly easy, the Noldor Spirit Horse easily outruns them after all. It allowed me to safely take this screenshot after all my troops succesfully retreated from the battlefield
After killing Eyegrim, I went to a corner of the map and circled around the Revenants so they would waste their throwing axes. After that, every revenant but one had either a 2 handed weapon or a couchable lance, so I just gave 2 shots to each of their heads and they went down. The other had a morningstar so I decided to kill the horse instead just to avoid any risks. Next came the truly tedious part: Circling for 1 hour around almost 300 angry zombies constantly throwing stuff at me. I switched to 2 shields and a Netherworld Charger to make it out in 1 session without having to switch horse in the middle of it. This was the final result of that first wave (We became hedgehogs
Next waves were easier as they more and more consisted of basic fallen that had no throwing stuff, so 2nd wave had 100 guys with throwing, 3rd wave had about 50 and the 4th and last only had 3. They all could fall down in 1 headshot so in the end I still had 300 arrows left in the inventory baggage. The battle took about 5 hours, 3 shields and 3 horses to complete
I also got the CKO secrets so everything is nice. I wonder how it will be to solo Eyegrim in 3.9.4 since his army is having some major changes.
As a side note, here's a silly quote from an EG knight before I smited him, and the new toy I found in a shop shortly after
