I wonder if the PH is a Goblin Mariner. I am in The Buried Sea with my druid tracking & killing Goblin Mariners for the past 1,5 week. No globmogger appeared.
Found him at loc -2500, 3450. PH is 'a goblin mariner'. He casts a snare that lasts 30 seconds (didn't catch the name) which I never resisted with 410MR and casts shaman spells. Doesn't summon. Couldn't pull him to shore either. Dropped the Suncrest Ritual Ring and Goblin Parts.
