Protego Duo was the incantation of a charm used to protect the caster from physical and magical attacks alike, and was fully capable of deflecting spells cast at the shield to their original source.[1]
It was a more powerful version of the traditional Shield Charm,[1] although it was not as powerful as Protego horribilis, Protego totalum or Protego Maxima.
