Jack of Blades's Mask, sometimes referred to as the Soul Mask, is the grisly-looking and instantly recognizable mask worn by Jack of Blades. The mask itself has the ability to trap and carry souls. Some speculate that Jack has used the mask to possess many Heroes over the centuries, granting him control of their body and making him appear immortal. This correlates with the fact that Jack's original physical form was broken long ago, through his fight with William Black. Warning: The Soul Mask cannot be removed after it is put on. (Can remove in Anniversary with a save glitch)
