Ok, so this really a question about how Fighter's Bravery class feature works.
The question is, Bravery says "anytime you gain the frightened condition, reduce its value by 1."
Dirge of Doom says "They can't reduce their frightened value below 1 while they remain in the area."
The Fighter argued that the Bravery triggers before Dirge even applies, and so never gets the frightened condition at all. I was wondering if there was a specific ruling on this.
