I have once more question.
For example:
Acid
Defense: Willpower + Firewall
Acid IC is about wearing down the defenses of intruders so that the other IC can finish it off. When Acid IC hits in cybercombat, the target’s Firewall attribute is reduced by 1 per net hit, reducing the effective defenses. Lost points are restored after leaving the host, at a rate of 1 point per minute.
What pool of dice use IC? Attack Rating vs Defensive Rating is for Edges not for roll attack. If Im hecker my attacks are Data Spike and Tarpit, or i can use Crash Program, but how attack IC?
