Piritus was a sorcerer of mediocre power. Unlike Shadowrage, Val, Taxrian and Trasta to a certain extent, whose destructive force comes from within, he needed items to enhance his. As weak as he was with the power, he was no fool. He knew that if others with my level of power were to find these artifacts, then it might encourage them to use it for their own ends

Shadowrage successfully took the hood before the Medovates could steal it for Taxrian. The hood increased his power ten fold, but as of now, he cannot remove it. This was revealed in The Darkest Wind.
