No I have screenshotted the text for Proof of Bravery.
You get them from only the level 75 versions of wodjin, mandara, hackman, lagusen and targonhaul. You must have the Beacon of Courage in your inventory to get the Proof of Bravery. Here's the link on the aus forums where I've posted the screenshot.

Oooook, thats a HUGE sigh of relief. My problem is, I never got an additional quest from either Laath or Parma. I obtained the beacon of courage, Parma goes back to default npc text, and Laath has the greyed out turn in for the reward.
Proof of Bravery (ID 209397) from the world bosses is not the same as Proof of Bravery (ID 240777) for the quests

.
Yeah, I didn't find the ID from world boss proof of bravery, just matched ID's with the old one and came with (the wrong) conclusion that you needed boss drops.
So if I understand this correctly, use beacon of courage near a downed lvl 75 boss's body, and you get 1 Proof of Bravery, do this x3?
I need to check in-game, because that quest was never available >.<
edit: btw, thank you for clearing it up Kista, you saved me from nerdraging xD
