Sense Blasters are one of Dex's inventions used in Neverseen when he, along with Sophie, Fitz, Keefe, Biana, Della, and the Collective, broke into Exile to rescue Prentice. They were working well until Councillor Zarina blasted and fried one of them with lightning causing it to explode.
Description[]
Sense Blasters are cube-shaped, with a timer on one of the faces.
