Items have two diffeferent traits "Fame" and "Power". Each trait is represented by a random value between 1% and 100% as iClops monsters have a random between 80% and 100% whereas weapons and pills (gimmicks) have a value between 1% and 80%. The "Power" value is important for staking because its working as a base stake indentifier.
Every Block a NFTeGG Surprise Series #1 Item is staked in the "Farm" Contract it will generate a reward. This reward can just claimed anytime in the overview or will be paid out with the final NFT withdraw.
If the Reward or Stake is removed before a mature time on 72 hours, the payout will reduced by 10%.
