I'm also assuming that her criminality rating is going up because of the successful hacks she's had, and I'm assuming that that criminality going up is what's now making it harder to hack past authentication and stealth programs.
My questions are though, having now acquired V1 for a handful (armour, commander, decrypt, delete, evaluate, mask, silence, stealth, transfer), i.) what should I focus on getting next? Virus V1? Mask or Stealth V4? ii.) And, once she levels up, should I favour Intelligence over Skill, or level them up equally? iii.) Is her criminality affecting her success-rate, and if so, should I focus on Armour and Silence?
