The tree of might is a special tree from a dbz movie. Eating a fruit from it adds 10,000 to your pl. Unfortanetly after the battle or sparr or whatever you lose the pl so its not to keep. Unfortunatly the tree of might has a guardian. The Tree of Might Guardians are very powerful and are almost impossible to beat. But when you get the tree you may plant more trees from the fruit or grow fruit or plant the tree somewhere else. 3 fruits grow each week.
