As in title: I would like to cast a long duration spell (let's say a simple "luck" buff using Entropy Sphere or a simple illusion changing my appearance) with at-will on/off functionality (as in, I want to be able to turn it on and off at will, without having to cast the spell again).

What I mean by on/off? For example:

• When it's off the permanent Paradox point from the buff (if applicable in the first place) is gone.
• When it's off there is no resonance from the buff radiating from me (so no way to see magic on me using senses spells, including sphere-based senses).
• When it's off, effects of the spell don't apply (I can think of several effects that might be good or bad, depending on situation).

The question is: how do I do that? And (if there are many ways to achieve that) what are my options?
