Given that the spell Irriseni Mirror Sight works through mirrors rather than directly scrying on an individual (and there is no saving throw against it), can people detect the spell when it is in use? The Effect is a magical sensor, but the spell itself allows no save and no spell resistance (and requires an actual proper mirror).
What would the difficulty for detecting the scrying be?
Detect scrying spell would work.
It doesn't appear that their is any mundane way to detect it.
correct that, it is a scrying subschool spell, so it would have a perception DC of 23 (20 + spell level) to notice.
Okay, thank you :)
