Broadband Noise Generator, Mk 3

Technological

When activated, this unobtrusive lump of metal and plastic emits an irritating sonic whine, aggravating bystanders’ senses. When you wear the activated upgrade and enter the blindsense or blindsight range of a creature whose sense is based on sound or vibration, that creature must succeed at a Fortitude save (DC = 10 + 1/2 the upgrade’s item level + your Constitution modifier) or its special sense becomes hindered: its blindsight functions as blindsense, or it loses its blindsense. This effect lasts for 1 minute, and whether the creature succeeds or fails the save, they become immune to the armor upgrade’s effect for 24 hours.
