Electro Graft Use has Prerequisite: Mechanicus Implants. The Augmenticist doesn't have access to Mechanicus Implants (of which one is the Electro Graft), so should this Talent not appear on the Augmenticist's advancement?
Can an Augmenticist take Electro Graft Use?
The Adept in DH also has access to the Talent, just allow it...
