How to complete Explorer Society Special Badges mission?

Question

Hello, I am doing the quests in Tibia and have completed the entire Explorer Society Quest. However, there is a part that remains open, and I have found nothing to help me finish it. It is called: Explorer Society Special Badges. And what is written in it is this:

You have been awarded the Sea Scout Badge for completing the Calassa and Frozen Trench missions.

Other Badges: None

Has anyone completed this mission? What do you need to do?

Answer 1

I found out how to set the quest status to 'completed' in the quest log.
You need to deliver 3 items to the NPC: Explorer Brooch Skull of Ratha Giant Smithhammer!
