How can I restart Serpents Fang quest? I did not kill this boss during the quest and I can not get the Upper Craglorn Cave Delver achievement.
Thank you,
Ned
Quest bosses aren't required for Delver achievements. For Exarch's Stronghold, you only need Grothuska and Ordooth the Corruptor (along with any attendants). Exarch Braadoth is not required.
