Grimrot baby

[Nobletoad]

So I'm pretty excited to start camping this hellish camp of Grimrot and I wanted to clarify two things first before I melt large portions of my brain from this session. Does the Grimrot ph in fact spawn every 6 minutes? I've been hearing people on the server who finished the aegis confirm this but on the old school archived forums and zam's i understand he used to be a 3.5 hour respawn on live. Also, which skele is the actual Grimmy ph? If I'm setting camp I would rather just keep killing the one ph than that whole mess, there's literally 9999 skeles there. I'm assuming it might be one of the 2 putrid skels that are like kinda-but-not-really under a tent? I read somewhere that grim's ph always wields a rusty bastard sword but not a single skele in the camp is holding one.

Any help would be appreciated guys!
