The Melon Dicer 3.0 is a LEGENDARYAxe, specialised for farming Melons. It grants +10☯ Farming Wisdom and the ability to receive random amounts of extra Melons.
It is recommended to use the Bountiful reforge on the Melon Dicer 3.0, as it grants a bit less ☘ Farming Fortune but more coins in general, which is the best option if you farm for coins.
When calculating the average luck of the Roll Em'++ ability, the Melon Dicer 3.0 gives the equivalent of ~155.2☘ Farming Fortune on Melons.
It is worth noting that it does not directly translate into ☘ Farming Fortune, as it does not give a guaranteed 1 extra drop per crop broken, it is merely an approximation.
