Neural-Net eraser

A Neural-Net eraser was a device used throughout the Clone Wars to protect against rogue battle droids. These devices became necessary for many beings who feared attacks by the Separatist droids. When fired, it released a streak of blue energy that destroyed a droid's internal circuitry and software, rendering the droid useless.

The servant droid Solis was shot with a Neural-Net eraser by Asajj Ventress, causing him to spasm and go out of control.
