Page 34: Cybertronic Enhancements
Q: Page 34 states that here are times when a player may opt to add cybernetic enhancements to a model(s) and when this occurs, theAI rating of the model is increased. By how much? When does my model move from mortal to AI?
A: Each enhancement moves you up one level. No level of enhancement will move you from mortal to AI. If you are mortal, you roll on the moral system. If you are AI, you roll on the AMOK system. If you are mortal with an AI rating, it only means you might be susceptible to certain powers and effects reserved for models with an AI rating.
