If you love discovering new and different things in the game, then you have to try out a couple of new Quests.   You will need to use your Fisherman or find a friend hat is a Fisherman to fix up a Red Herring and a Mud Puppy (these are two new 'Big Fish' in the Sygian Abyss.
Something Fishy - Found in the Underworld, the Something Fishy quest is given by the grey goblin Barreraak. 
Scraping the Bottom - Found in the Underworld, the Scraping the Bottom quest is given by the green goblin Xenrr. 
One gives you a cool ring which polymorphs you into a 'Gray Goblin' and the other gives you a Fishing Pole that Polymorphs you into a 'Green Goblin'.  These two should work just like the 'Orc Mask' and the Goblins should not attack you, but currently it does not change their aggressiveness towards you...
