Psy-Jammer

Somewhat esoteric examples of techno-arcana, these devices can at least partially disrupt psychic energy and offer some degree of protection against the dark arts of the psyker and the witch, Expensive and rare, their use is largely restricted to the agents of the Holy Ordos, the Mechanicus itself and those among the Imperium's elites whose paranoia often matches their their vast wealth. Much more powerful examples of anti-psy technology do exist but they have a tendency to be exceeding rare often unique. Psy-jammers can be obtained in two types: a protective amulet and a cranial implant. The amulet has the disadvantage that it can be physically removed; but while the implant cannot be so easily countered, it can have unpleasent long-term side effects to the user.
