Pandemonium Loop is a Legendary ring in Diablo III. It requires character level 12 to drop, and can only be obtained from Horadric Caches from Act V or Act IV. It is one of the two rings in game that can roll a chance to Fear on hit (the other being Rechel's Ring of Larceny). The explosions cause 800% damage as Physical, Fear lasts 3 seconds and only affects lesser enemies. With some luck, it allows keeping multiple enemies continuously Feared, but is only effective against big crowds of foes (including the Illusionist elites).
