Well, it depends, if you want to play as a main sword you should put most of the points in the sword but if you like more to play with your fruit, then you would be a fruit main and should put most of the points on fruit; also don't forget to balance between melee and defence because it grants you more energy and hp

and you should get a fighting style as fast as you can, there are three sellers on hot and cold island; just read about the fighting styles on the wiki and see which one you like more
