Question: Does datasucker help prey?
I guess not, but an ICE may be passed before the encounter with it is over. I couldn’t figure this out from looking at the run timing chart. It doesn’t specify when an ICE is passed (after 3.2 but still during the encounter or at 4.1?).
Answer (figured out on UK Netrunners group on Facebook) datasucker doesn’t help. Pass is defined as after the encounter or approach step if the run continues. At which point datasucker stops reducing the strength of the ICE. (Get your Bishops out folks).
