How exactly do Minh Thi Phan's unique abilities work?
Does she gain one additional die on every skill check while having an ally / another investigator in the same location? Or does she simply add +1 to the result of every die rolled in those skill checks? I.e.: Do her unique abilities work like the one of the common skills ("Fight": +1 to fight checks) or like the grapple skill ("add +1 to each die you roll")?
