Woodcutting Energy, or NRG, determines how many times you can cut trees.
Wood NRG is given to the player at a rate of 1 every 20 minutes. The amount of NRG gained can be increased by 1 with the use of the two NRG+ Ascension Upgrades, while the time it takes for NRG to increase can be reduced with the NRG Reduction Trophies Upgrade. Maximum Energy can be increased with the Energy Capacity Woodcutting Upgrade. The maximum energy is 1050 at level 250.
