Collecting Soiled Rags

So I'm trying to collect Soiled Rags for a quest and I can't seem to find a good map with a spawn of Elderwraiths. =/
The Evil Dead map reduced the spawn significantly to only spawning 1 or 2 every 15 sec or so. I tried looking at the Evil Rising map but it seems they're replaced with ordinary Wraiths. >.<
Is there a map with a good spawn of Elderwraiths now? =(

I think there's still a good amount of Elderwraiths in the map that the far bottom-right portal of Bent Tree leads to. If not, then try the map where Lukan resides, I recall seeing a decent amount there while trying to look for Headless Horseman/Bigfoot.

Does the quest still give the same exp prebb?

Yes, as well as Meso reward.

No, the experience is less, but the mesos are the same.

Pretty sure you can find them at the hidden street in phantom road.. been a little bit since I went there.

Pro-tip for spawning tons of Elder Wraiths at the first map Alilatias mentioned: Kill the Leprechauns (First or second form, both count as a monster kill, though it's obviously recommended to kill both.

I spawned so many Elders that they took up pretty much the entire spawn for the map, no more Leprechauns would even spawn after.
