The Rainbow Crystal Staff is a summon weapon dropped by the Moon Lord. When used, it summons a diamond shaped crystal that attacks nearby enemies with rainbow colored bursts of twinkling light.

  • While higher in damage compared to the Lunar Portal Staff, it has even greater difficulty hitting fast moving enemies, as there is a delay between targeting enemies and the crystals resulting explosion. It is however, much more effective against slower moving enemies and most bosses as a result.


  • The quote in the tooltip is a reference to a Popsicle commercial from the 90's where a teenage boy consumes a Popsicle, then proceeds to excitedly state "The colors, Duke, the colors!" to his dog.
