This trick takes patience to do. Every time you get a Mana Seed, you will be able to increase your magic's level. But, you have to use the magic a lot to make it increase (which takes a while). Once you get your magic spells in level 7, they will start to be super-powered. They will not do it every time, but you will know when they do. Once the spells get into level 8, the spells will be super-powered other spells will be super-powered.
