Spectrum

Spectrum is a Legendary sword in Diablo III. It requires character level 30 to drop, and can only be obtained from unique monsters in Whimsyshire or Whimsydale, at a very low chance. For example, it can drop from the Pink Rainbow Unicorns.

While it does not have any exclusive stats (aside from All Core Stats, that is, Strength, Intelligence, Dexterity and Vitality, which can go above the normal limits), it is sometimes sought after as a transmogrification choice due to its unique look (the handle is taken from angelic blades like Skycutter, to name a few).
