This guy u will need to go to Sycraia Underwater Ruins (Abyssal Zone). Search how to reach Sycraia Underwater Ruins (Abyssal Zone) BDO. U will find him after run a while. U r W!!!
If you have troubles with screenshots - after teleporting to the abyssal level open Monster Zone Info, find Sycraia Underwater Ruins (Abyssal) and click on Recurring Quests from Gormin. It will not give you right autopath, but show his location.
