Hollowed Drums, Mk 5

Necrograft

Hollowed drums are inserted into your ears and replace the standard eardrums of your species. This necrograft can be activated or deactivated as a swift action. When activated, it deadens sounds you hear, reducing their volume and emotional impact to grant you sonic resistance, a –2 penalty to sound-based Perception checks, and a bonus to saving throws against mind-affecting effects with an auditory component (such as suggestion) that vary based on the model.

Mk 5 hollowed drums grant a +3 enhancement save bonus and sonic resistance 20, and grant no penalty no Perception checks while active.
