Yes. Genshin Impact - 300 Primogems is free right now on Xbox, with nothing to pay.
Do I need the base game?
Yes. This is add-on content, so it attaches to a game you must already own. Claiming it without the base game will not give you anything playable.
Where do I claim it?
On the official Xbox page. We link straight there — we never host game files or act as a middleman.
