Gemini Field Engineer Mk III
Upgraded version of the Field Engineer. 5 nano constructors for decent healing and 4 additional nano binders for continuous healing when out of energy.
Blink module for quick reach of crippled allies or fast escape when the healed one dies.
Light armoured , agile (add strave moves on Q and E for more moveability options) and optimized for healing.
Just don't get hit and stay out of the line of fire.
