I have one (1) Stellar Blade / Nikke collab key for your game.
I'm lazy so just post your server and a screenshot of your Scarlet proving you currently don't have the skin. I'll reply with the key for the server of the first person to do this. Then it's a free for all who redeems it first.

If you already have the skin it will consume the key but you won't get anything, so don't be retarded.
