Description
An Awareness Shield reduces or eliminates the emanations of magical disturbance that accompany active magic or concentrated magical energy.  This paradigm serves to alter reality within the aura of the recipient, then masks that alteration to hide most magical emanations from the recipient.  It is still possible to detect some emanations, but only for a highly talented observer.   The emanations would also appear to be much fainter than they actually are.
Effects
Potency for this paradigm remains variable, making less effective versions of this paradigm possible.  The high intricacy costs associated with altering reality and masking that alteration make even lesser versions somewhat expensive.  For example, cutting the potency in half only reduces the total cost by 10 points for both spontaneous and optimized castings.  More powerful versions are also possible, in optimized form.
Note that casting this paradigm at full potency is impossible without some optimization, since the spontaneous cost exceeds the Configuration Might of Sorcery for Transformation / Reality effects.
Scope Basic Scope (2)
Scope is altering a Form (3)
Range is Personal (no cost)
Area is N/A
Duration Interval is one hour (Impressive: 10-20)
Potency Enhancement / Hindrance: this paradigm adds a +10 Hindrance to Awareness Trials for any observer, thus effectively hiding the magical emanations of the user. (20 points)
Intricacy Nature of Change: this paradigm alters Reality (Epic, 21-35 points).
Perception/Illusion: this paradigm affects one sense (Awareness): Slight (1-3 points).
Total Base Cost Spontaneous: (81), Optimized: 55
Temper Aspects Maintain is useful
Anchor would seem to be a natural, but wouldn't normally be possible for a full-potency version - a reduced potency version, however, might be possible.  In that case, Duration would be One Action Interval, bringing Scope down to Moderate (total 5 points), and Potency would need to be 8 points or less, bringing the cost within the Configuration Might of Sorcery.
Notes
A version of this paradigm with Range: Touch is also possible, allowing the sorcerer to mask magical emanations from another being or object.
