I will be implementing the new Horror Adventures rules for fear in the Strange Aeons Adventure Path. I'm wondering if these new fear tiers were intended to only be reached through multiple "stacking" from fear-inducing effects. As these rules stand, the Horrified condition could only be reached from several instances of being Frightened, which is probably a good thing since its just inches away from coupe de grace. Or is it intended that the GM will determine which story events justify as more Panic-inducing, Terrifying, or Spooky events?
I'm also wondering how to appropriately implement these with previous existing creatures that have fear-inducting effects. Some creatures with fear auras might be arguably more suitable to giving the Panicked condition instead.
