Multi Discipline Cards, Three way cards, Requirements

In the rulebook is stated that

"Some library cards have multiple Discipline symbols on the attribute bar. Some of the effects listed on these cards require one of the Disciplines listed, while other effects require another listed Discipline, and some effects require the vampire to possess several Disciplines. Each effect shows the icon(s) of the Discipline(s) required."

I have covered all possible combination of cards, including



a card who has three different (combined) effects

a card with three different and separate effects

a card with 3 different effects with 2 different disciplines

a card with 2 disciplines required to have effect.



In which case the discipline is required?



I think only if the discipline is used, so basically a True Brujah can play Illegalism with presence (ignoring it has celerity printed on it), and you can't use Hide the Mind to cancel a Anestethic Touch played with obe.

When a card is being played, it requires whatever discipline(s) you're using to play it at that time - even if there are other disciplines that could be used towards it. For example, Denial of Aphrodite's Favor could affect Illegalism if you chose to use it with Presence, but not if you didn't.

At other times (e.g. when in your hand, library), you can treat it as requiring all of the disciplines available. For example, you can fetch a Thaumaturgy/Visceratika card from your library with Spirit Summoning Chamber, even if you intend to play it only with Visceratika.
