Dynasty weapons.

Hello everyone. I'm new here, so please don't blame me if I post in the wrong place. I have some questions and requests. Question: I have 21 Dynasty weapons. How do I get the Flaming Dragon Tongue sword and the Sar-Agretta staff? And a request: Guys, does anyone have an extra key for weapons from the Heroes of the Kingdom? I'm willing to buy it. I just missed it. If anyone can sell it, please do. And if anyone can sell the Chaos Sword and the pre-order hero, please sell it. I don't want to buy the content with the game for 400. If anyone can sell it, I'll reward you generously. There's not much left. Please help me out.
