Landmark Crafting:
One utility of Landmarks is combining your less rare NFTs and upgrading them to the next tier.
You need 4 copies of each Landmark to upgrade to the next tier;
4x Common → 1x Rare
4x Rare → 1x Ultra Rare
4x Ultra Rare → 1x Legendary
This is another way of obtaining a high-rarity Landmark aside from relying on pure luck in the Gacha-style minting.
Note: to be able to use crafting, you must allow the contract to be able to transfer Landmarks NFTs on your behalf. Don't worry. It can only transfer NFTs under the Landmarks collection and not your other NFTs. You can read more about the OpenZepplin's isApprovedForAll function here.
