Daily Punch 4-19-20 Gremlin Storm resonance for Shadowrun 5e

I’m at lunch watching several people beat on their cell phones because of poor receptions.  What if it IS technomancers?!

Let’s  make that a reality!

Gremlin Storm

Target: Area • Duration: S • FV: L + 3 

No one likes to listen to rando’s phone calls around you, so you just shut them all down around you.  You concentrate on an area in meat space. Make a Software + Resonance [Level] test.  Much like spells you must get at least three hits to target the area with the area being [level] meters in radius.  Any net hits cause noise equal to level + hits over three to any device that enters the area that fails a Logic + Data Processing test vs the [level].

Thoughts?
