Need help locating spawn points!!

[Qualtar]

First off anyone willing to share is way cool, and thank you. I am looking for where mainly Nightmares spawn. I know the spot in fire cemetery, there has to be other locations. Where and how to get to the nightbear, and lastly the white steed. TIA!!

White steed like the "rare white horse". ? Not sure i thought just random rare spawn. Night mares are in pretty much every rune library around so just check those. Night bear. Good luck
