Easy

You dont need to get facecrusher's ring, you can easily hold down "ctrl-Shift-and the
symbol
~ and then type in facecrusher's ring, including the appostrophy, alot of people make this
mistake. =) also if you want to do it the hard way, defeat all the monsters, and break
everything on level twelve, if you can find it after that, it means that you already
killed the monster that had it, and you just missed seeing the ring, scout the level over
again and look for it, to make it easier type in -Discoverall- with the cheat, hope this
helps =)
