Energy in WingStep is represented as a Cooldown bar. When the Cooldown bar returns to 0, the Performance bar will be fully charged.
In each NFT Sneaker, you will receive a full Performance bar, which will determine the maximum time you can train and earn.
Once your Performance bar is exhausted, you won't be able to earn more rewards even though you can keep training. Then you just have to wait for the Cooldown bar process until your Performance bar is fully charged.
Each NFT Sneaker will have a different Performance bar and Cooldown time. You will receive rewards commensurate with the performance of the Performance bar. The larger the NFT value, the more performance and rewards.
The Cooldown and Performance bars can both increase or decrease when you Evolve NFT or inlay GEM into that NFT.
If you want to reduce the Cooldown time so you can continue to earn, you can use the CD Ticket (received upon opening the Secret Box) or use the token to buy at 200 WST for 1 Cooldown bar.
You are only allowed to buy 1 time per day for each NFT you have.
