# Other In-game NFTs

### SNW Hero(es)

Whenever Mystery Boxes are purchased, the Hero-NFTs will be minted immediately. But before opening, you can choose whether to bind with existing white-listed NFT communities.

By strategically partnering with [Starsharks](https://starsharks.com/), [Yolee Universe](https://twitter.com/YoleeUniverse), [Melaxy](https://twitter.com/MelaxyGame), [Prometheus/MGA](https://twitter.com/PromethMetagame), [Immortal Cat](http://immortalcat.io/),  [Miningverse DAO](https://twitter.com/MiningverseNFT), [Huobi Global and Huobi NFT](https://twitter.com/TheHuobiNFT), [Bybit](https://www.bybit.com/) ([Yeehagames](https://yeehagames.com/) & [Midgard Saga](https://twitter.com/RealMidgardSaga)), SNW is now opening for active application of engaging more precious NFT communities into this Social Meta Space and jointly dedicating to co-construct, co-upgrade and co-govern this one-for-ALL metaverse aggregator.

#### **Rarity**

When minting, different rarities of Heroes will be randomly generated:

#### **Synthesis Functionality**

In order to improve the liquidity of those Heroes with relatively lower rarities, we offer the Hero synthesis function by enabling multiple lower-rarity Heroes to synthesize and upgrade into a Hero-NFT with higher rarity.

#### **Upgrade Functionality**

Consuming a certain amount of $SNGold and experience points can upgrade and get more attribute points.

### Skill-card NFTs (TBA)

Hero-NFTs can learn skills by consuming Skill-cards. Skills can improve the mining capability when exploring the PVE underground dungeon and PVP arena.

* Stars: the reference value of the Skill-cards' rarity in 1-5 classes. The obtaining methods are as follows:
  * Skill-card Mystery Boxes Opening: 1-4 stars;
  * PVE Exploration: 1-5 stars;
* Level Upgrade: Skill-card's level can be upgraded by consuming several skill cards (ONLY with the same title name and the same level) + a certain amount of $SNGold🪙.
