Hi
After killing 100 Cobra, I went to Foxhill Tomb to kill Felis Berserker (-222, -266).
Unfortunately, there is only an empty platform.
I searched the lower floor of Foxhill but Felis is nowhere to be found.
I waited on the platform for two hours (Invigorate) but the boss did not appear.
Do you know how to finish this quest?
The felis berserker only appears on realm 5. I realize it's been a while since you posted. I don't know how his regeneration works, though, so any input on that is appreciated.
