# Standard level up As described in the [nft-assets](https://nbmofficialwiki.gitbook.io/nbm-shadow-depths/overview/nft-battle-miners-official-wiki/iv-nbm-nfts/nft-assets "mention") section, in NBM, NFTs have a level ranging from 1 to 5. Once an NFT reaches level 5, it is possible to improve its rarity. However, NFTs that are not at level 5 need to be leveled up to level 5 to be eligible for Fusion. The first option players have to improve the level of their asset is the Standard level-up option. **Standard level up:** While using standard level-up, only one resource is needed, depending on the type of card being leveled up: * [actium](https://nbmofficialwiki.gitbook.io/nbm-shadow-depths/overview/nft-battle-miners-official-wiki/iii-resources/actium "mention")for Active cards * [minium](https://nbmofficialwiki.gitbook.io/nbm-shadow-depths/overview/nft-battle-miners-official-wiki/iii-resources/minium "mention") for land cards * [constructium](https://nbmofficialwiki.gitbook.io/nbm-shadow-depths/overview/nft-battle-miners-official-wiki/iii-resources/constructium "mention") for Construction cards The token cost is calculated as follows: Cost = (2000 x Rarity x Next level)\ -with the rarity being 1 for Common, 2 for Rare, 3 for Epic, 4 for Legendary and 5 for Ultimate. For instance, if a player wants to level a: * Common active from level 1 to level 2, the cost will be equal to 2000 x 1 x 2, or 4000 Actium. * Epic land from level 3 to level 4, the cost will be equal to 2000 x 3 x 4, or 24000 Minium. However, additionally to the cost in token, each level-up requires the player to sacrifice a lower rarity card. For instance, leveling up a Rare Land card consumes a Common Land card, while leveling up a Legendary Land card consumes an Epic Land card.

\*: During a standard level up, the cost in tokens is the same for each category (Actives, Lands, Constructions); only the type of token changes.\ \*\*: Each standard level-up requires sacrificing a lower rarity card from the same category (Active for Actives, Land for Lands, and Construction for Constructions). Note: Both Common and Rare standard level-ups require Common cards as burners.
