Some of them are NFTs, but most of the blockchain items that drop inside Lost Relics adventures are FTs, fungible tokens. This is because if there is a supply of 500 of one type, all of them must be the same, with same stats, name and rarity and since they aren’t unique they aren’t NFTs.
This however doesn’t change the market value. The most valuable items in Lost Relics are fungible tokens (FTs) not NFTs.
The actual NFT’s in the game are usually skins (outfits), pets and other cosmetic items.
