So this is a bit old, but I just ran into this issue.
If there are 2 hounds. The first one Bays, and I am hit with fear I run away.
The second Hound Bays (trying to hit the rest of the group) I succeed my save.
Now as I am running, if the second one makes noise (the one I made the save on). Does anything happen? Are the sounds considered "the same".
On that note does Panic also have frightened effects (like a stacking tier?)
