I don't fully understand your question, and I can't see any cardtext related to the question.

Name: Nickolai, The Survivor
[Third:V]
Cardtype: Vampire
Clan: Tremere antitribu
Group: 4
Capacity: 6
Discipline: aus dom pot pre tha vic
Sabbat: Nickolai may gain 1 level of any Discipline another of your ready vampires has at superior as a +1 stealth action that costs 1 blood.

Nickolai can gain 1 level of any Discipline.... as an action. You don't need a Master: discipline card to represent that, if that is the question.
