## Skill Detail

<mark style="background-color:yellow;">**The SKILL cards of NFTsBattle is ERC721 token,**</mark>

but the value of the SKILL cards (such as damage, firing range.) will not be recorded on the chain, but only in the game.<br>

This practice is to achieve the perfect balance and continuity of the game,but it doesn’t mean that player’s NFT has no value.<br>

<mark style="background-color:yellow;">**We hope that each card in the market has a basic price, not just some powerful SKILL cards to be the limelight.**</mark><br>

Therefore, through the update of the Meta version,NFTsBattle will make some values adjustments of SKILL cards and HEROes in the game to achieve game balance.<br>

Combined with player’s strategy, all SKILL cards can come in handy in battles and maintain the value in the market.
