Biotic Implants and Bio-amps

Biotics manipulate mass effect fields using dozens of element zero nodules within their nervous system that react to electric stimuli from the brain. All biotics seeking to wield their abilities on a usable level are fitted with an electronic cybernetic Biotic Implant at the base of the skull. Once the implant is installed, it can only be replaced or altered surgically, and thus classified as Mechanical Augmentation, though it is merely an interface port into which Biotic Amplifiers or Bio-amps, SD card shaped chips that allow biotics to synchronize the nodules so they can form fields large and strong enough for practical use, are plugged in.

Amps can improve a specific discipline or talent, and Implants can fit a variety of amps. In addition, there is a growing market for modifications and add-ons. The finest quality implants and amps are manufactured by human biotechnology firms, followed closely by those made by asari artisans.

Košice Britva
The Britva (Slovak for "Razor") is a biotic implant designed by Košice fabrications, First implanted in 2146 and brought to active service in the mid to late 2140's, it has undergone 12 versions.
 * Košice Britva 3 - Used by Kaidan Alenko in 2152.
 * Košice Britva 10x - Used by Sweetie Belle in 2168. Even though the implant magnifies her abilities marginally when equipped with the correct amp, it causes frequent migraines, and may cause a nosebleed when pushed towards its functional limit.
