[List of flashpoints (normal and hardmode)]

What are the requirements to start some of these Hard Flashpoints?

 

I have the quest to do Hard Boarding Party, but I have not yet done it because I haven't been able to find a full party of people who are eligible to do it.

[Tionese War Leader's Belt]

There's two available for Synthweavers to craft.

 

 

Edit: Wait, I don't think they craft Tionese though, my bad.
