I am here exploring terracore game again, I recently started to explore holozing game as well. I was seeing terracore #nft section and realized that there is a pure luck factor based on which we get a NFT.
I saw a table where there was written the drop chance for rare, common, legendary NFT.

If you can buy a legendary crate that I think might be more costly then your chance of getting a legendary #nft increases.

We can see that there is a 17% chance of getting a non legendary item from the legendary crate. That is why I said that there is also a luck factor indeed there is a huge luck factor to get a nice one.
But yes no matter what this will make people buy this NFT crate so that they can easily get a legend item. If I was playing the game I would have bought this crate only.
thank you
