Each time the Runner accesses an agenda from this server, he or she must suffer 2 net damage as an additional cost in order to steal it. This applies even during the run on which the Runner trashes Ben Musashi.
No MWL Entries for this card.
Can the Runner still steal an agenda if they prevent some or all of the net damage incurred by Ben Musashi?
If the Runner prevents even a single point of the net damage incurred by Ben Musashi, then they have not paid the additional cost to steal the agenda and therefore do not steal it.
