Exemplary Finisher (9th) let's you remove a target's temporary immunity to your demoralize action. If the opponent is still Frightened 1 from your Demoralize, can you attempt to Demoralize them further?
Like let's say you are a Hobgoblin with Agonizing Rebuke. You Demoralize your opponent with 1 action and get a Success. You get Panache. They are Frightened 1. You use the Panache on a Finisher as your second action. For your third action, you can then Demoralize your opponent again.
This has the added benefit of:
• Potentially getting a Critical Success to upgrade them to Frightened 2.
• Activating Agonizing Rebuke a second time to double the ongoing damage.
• Regaining Panache.
Stacking multiple Agonizing Rebukes, especially with Agonizing Lash, seems pretty strong.
