The Stealth Booster is a compact, high-tech device designed to enhance the user's stealth capabilities. It features a sleek, angular design with a matte black finish to avoid reflections, adorned with subtle blue glowing circuits that pulse when activated. The surface is smooth with minimal texturing, except for a few engraved tribal patterns that hint at its post-apocalyptic origins. The device is small enough to be worn on the wrist or attached to armor, with a central circular interface that displays activation status.
