Here's how these things are calculated:
| lvl / 1 | +1 | 2 |
| 6 | +1D | 3 |
| 10 | +2D | 5 |
| 14 | +3D | 7 |
| 3 | ability | +1 |
So... cyberware that gets your resistance attribute from 3 to 4 would cost 3 points of income (= level) and take up 2 slots.
Dice gained via cybernetic enhancements are not simply added to the Talent or Attribute Dice. Instead they are rolled seperately and added to the highest Talent/Attribute Die; rule of six does not apply here.
Example: Molly has reflex enhancements (+1D). Her regular Initiative attribute is 4D+3. At the beginning of a combat round she rolls: 6,5[5],5,2 => 11 + 3 => 14 + Cyberware Die [6] => 20
Ability refers to any type of additional ability, other than the purely cosmetic, a player wants a piece of cyberware to have.
