# How does using different tools and land affect mining time and rewards? Gold Female Nordic 130
• Updated

Explorers select a Land NFT (Land) to mine on and up to 3 Tool NFTs (Tools) to mine with. Both Tools and Land have attributes which impact the Trilium and NFT rewards players get when they mine. Those attributes are charge time, Trilium Mining Power and NFT luck. These NFTs have utility in the Alien Worlds Metaverse.

Charge time is the amount of time that must have elapsed since you last mined.

• Tools have a ‘charge time’ associated with them which is the time, in seconds, that must
have passed since you last mined.
• If three tools are being used, the longest 2 charge times are added to derive the
charge time.
• If two tools are used, the longer charge time and half of the shorter
charge time are added together to give the total time that must have elapsed
since last mine.
• Land has a charge time multiplier. The charge time in seconds given by the Tools is
multiplied by the Land’s charge time multiplier.
• Trilium Mining Power (Power) is calculated as follows.
• Tools have a ‘Trilium Mining Power’ percentage; ‘Trilium Mining Power’ % of all Tools
used in a given mine are summed.
• Land has a ‘Trilium Mining Power’ multiplier which is multiplied with the sum of the
Tools’ Power percentages.
• NFT Luck impacts the chance of receiving an NFT from a mining action and is calculated as follows.
• Tools have an ‘NFT Luck’ percentage; ‘luck’ % of all Tools used in a given mine are
summed.
• Land has an ‘NFT Luck’ multiplier which is multiplied with the sum of the Tools’ luck
percentages.

Note that the PoW reduction (symbol in the lower left of the card) does not significantly affect mining delay, or mining rewards at all. For more information about PoW reduction, see this article: PoW reduction
