So couple questions on 2 components
1. Cypra Pattern Drive (Koronus)
2. Shadow Field. (Hostile)
They each mention a +15 and a +20 to silent running rolls but -15 and -20 "to detect"
Just to be totally clear, does it mean on a contested roll you get +15 and your enemy get -15 giving you 3 degrees of success almost right off the bat?
Or is it if you're using it you get +15 to silent but suffer -15 to your augur readings?
The first seems insanely powerful while the second would seem to make sense, I mean if you're running a shadow field it should probably scatter your sensors as well.
Thoughts?
