Did this today and OOT was has been broken so access was only from the Butcher-block zone. On the far west side of the zone is the Dock you land at coming from freeport ( 1071, 7090 ) and north of this is a cluster of small islands with lev 4-9? goblins (-1290, 7516) . Nerb was at the bottom of the ocean next to the eastern island (2067, 6977) . OOT water did not have the distance haze like other water so he was visible. Killing him did not spawn any other mobs.
Edit: Returned to OOT several hours later to see if Nerb was at a spawn point. He was where I origonally found him, underwater .
