Supreme greenfingers is a tier 4 aura that can be bought from the Loyalty Programme Shop for 61,000 Membership Loyalty Points. This aura prevents Farming crops from becoming diseased and provides a 10% chance of increased crop yields. Note: The disease prevention only works during the period the aura is active. It is not true that it will prevent disease for the rest of the growth time.
It is activated for 20 minutes and has a recharge time of 1 hour. Also, as with all auras, if the account using it is logged out while the aura is activated, the timer will continue to run.
