One contact at a time only limitation.
Accessibility.

Not really. Accessibility is a condition necessary for the ability, as a whole, to operate. It's not clearly RAW to apply that to only part of an single ability (as opposed to, say, a few levels of a levelled ability). And there's no frequency with which this condition occurs. It'd be "Accessibility (Never)".

I have no objection to a catch-all "Limited" if there's no better term, without having to bend Accessibility out of shape. The GM is determining the percentage reduction in either case.
