Necro Soloing from 55-60. I need help.

[Encroaching Death]

Alright, my Necro is 55 atm. I'm looking for the next solo spot.

I know of a few safe spots, but they're pretty permacamped.

I also know the popular spots are upper floors of CoM and Howling Stones.

I'm leaning towards CoM because I'm more familiar with the zone. I have never been to HS. Not once.

I know of the levitate trick to get on the 2nd floor of CoM, but I'm not 100% sure how to do it. And then I don't know what to do from there. I don't know the 2nd floor camps, dangers, tricks, etc.

Any information or help with soloing on the 2nd floor of CoM would be awesome, if possible. HS can wait for now. I'm not even confident I could solo getting the key for it..
