I've noticed that most schools have 1 or 2 craftable spells. Like for example, has Savage Paw and Samoorai. Has Goat Monk and Weaver. Has Winter Moon and Handsome Formori. Has Keeper of the flame and Ninja Pigs. Has Deer knight and Lord of Night.
However, the schools and only has one spell to craft. Why dont you make some craftable spells for and . Like maybe can get the rank 5 spell Magma man that does 50+600 over 3 rounds. For ,they can get Rank 6 Cloud demon that does 700 and gives 25% to all spells.
KI, please consider in the future to make all schools have the same number of craftable spells so that way it can be balanced.
