Mechanicus implants has been the same copy/paste description since Dark Heresy. Ironiclally most of the talents related to them have been removed and replaced with other implants. Am I going out on a limb if I were to suggest we are now expected to roleplay these implants?
The Electro-graft is a small port that is grafted into the nervous system. Once a recipient has been properly trained, this allows him to interface with machine data ports and certain types of data nets. Electro-grafts can take many forms, such as skull shunts, finger probes, or spine jacks.
You can plug into stuff, handy for downloading/uploading information.
Cradled within the cyber-mantle is a power unit known as the Potentia Coil. This mass can store energy and produce various types of fields. Coils come in many types, from small crystal stack affairs to bulky electrical galvinators.
You can use you coil as a power source. Plug your sholder glow glob in sow it never runs out of power. Plug your stummer in so you never need to recharge it. Hell plug your laspistol in so it doesn't have a clip, and just draws power whenever you need to fire.
Does any of that sound reasonable? Thoughts?
