Create Magician without Implants->Finalize->Implant Aug->Increase Magic Back to original value.
The cost is calculated from the pre-implant magic rating, but should be calculated from current magic. (IIRC SR3 handled that differently.)
IE
Magic 4 max. 6
Install Trauma Damper - Magic 3 max. 5 Ess 5.8
Increase Magic to 4 for 20 karma (current HL price 25 for Magic 5(4))
