The only thing it was good for was to raid one especial hut in the marshes north of Swamptown. The description was something like "... there is powerful treasure scattered on the floor." However when one of your characters not carrying the Fizbin tried to take it, he died instantly. With the Fizbin, the treasure could be taken, no problem.The one bad thing that I specifically remember, was that you could use things called "Quatloo coins" in a particular room in Slithercult Stronghold to boost your stats. They worked fine - as long as the character was not carrying a Fizbin. I can't remember now exactly what happened, but it wasn't good!
There were other things, but it has been so long ago since I played the game that I cannot remember them, and I won't have access until I get some things in my setup sorted out.
