About the rewards during livestream of World Championship 2019

[Inqui]

Greetings,

So, about the B&S World Championship 2019 and its livestream Twitch rewards.

As mentioned on https://www.bladeandsoul.com/en/news/2019-world-championship-livestream/ there will be rewards for viewers, but there is not quite that much information provided on how it works.

Do i need to link my twitch account with game account for this, if it even is possible? (Since we use the desktop twitch, how will the rewards integrate with our accounts?)

What do they mean by "Twitch Extension" that we can interact with?
Is there any guarantee of actually obtaining the special outfit itself?

 

I just want to prepare myself for this, and certainly avoid any issues or unnecessary panic when i see that it is not working, or something has been set incorrectly.

If anyone knows, i myself, and perhaps some other would appreciate any information regarding this reward system.
