What should I gift my boyfriend on his birthday?

My (22F) boyfriend (22M) has his birthday this month. We've been in a relationship for over a year, and during this year we've given each other multiple gifts. He's very thoughtful in his gift-giving, believes in grand gestures. We are very different financially, he is very rich, the kind I'd only heard of, before meeting him.

Recently for our anniversary he got me a very expensive present which I would never be able to afford. I want to return the favour, though he's not the kind of person who would expect me to give an expensive gift just because he did. But he gives gifts a lot of thought and wants a lot of thought put into his.

He's a fan of marvel (esp. Captain America, Wolverine, Daredevil), Game of Thrones, is a gamer. He had previously listed some of the things he wanted, like Captain America shield, Katanas, Jon Snow sword, etc, the genuine versions of which I can't afford. I've already gifted him perfumes, clothes, letters, and wanted to gift something different.

My budget is up to ₹3000. What should I get him as a gift?
