Passivity is a part of the Awoken Aspect of the Marrow Fysa.
Active magic is switched to a passive magic-- that is, active or controllable effects now only occur passively. This applies to ALL magics on the user.
These magics are either constantly occurring OR they occur outside of the user's control, triggered by emotion or time. This decreases the power of the magic, but also decreases the cost to use it, allowing it to occur more frequently.
