Where to farm nirncrux? — Elder Scrolls Online
WEBCorrect, only ore/wood/cloth nodes are where you can find nirncrux. Nirncrux will also drop very rarely on Craglorn animals that drop hides (both overland and in dungeons). I've only had this happen to me twice in the game ... since Craglorn debuted as a zone in May 2014. Options #18.
