Good Farming Spots For Underworld Crypt Keys?

Ok, so I'm trying to get enough Charon's Brains so that I can get that awesome fire sword in the Underworld Crypt, but I have one problem... I can't find any key guardians for the place!!!! Can someone please tell me a good place to farm for these? Thanks in advance!

 

There is no definite grinding spot for the keys, just look in level 20 areas and eventually you'll stumble upon a guardian. I found most of my guardians near Ancient Nemract.

 

Alright thanks, I'll try to afk around ancient nemract and see if any appear... The only ones I've seen were on the path towards ancient nemract, so I'll keep an eye out for them

 

maybe in the graveyard near the quest having to do with sayloros? (correct my spelling)

 

Ok

 

I got like 7 keys in 1 hour ._.

 

I don't know quite which quest you're talking about, but then again I don't do many quests myself. Also I'm only level 36, so I won't be able to do too many quests anyways.

 

I had to kill several of those Crypt Guardians to get a bow for my archer. I found that they tended to spawn around where the "Pit of the Dead" is (around x:360, z:-1960).

Also, when I was searching for the guardians I found that they hardly spawn in Saint's Row/the church or within Ancient Nemract. They only seemed to spawn on the strip of land to the north of the location mentioned above.
