After scouring the threads for tips on catching a Ghostface prior to Deep Caverns, I was led to believe that the only place they could be found was the sewers next to the Acid Hunters lair. Well, I just caught one in the Black Sea in sector (A-1)6 (see attached screenshots).
Don't know whether this is an extremely rare random event or whether this is a standard location for Ghostface. Just thought people struggling with the fishing quest might want to know this...
