lets say for example it starts with 10 mana and it gets upgraded and it adds a special move, it then requires more mana like 30. the next level it doesn't add a different attack but increases efficiency and reduces the mana required back to 10 now this repeates for the next few upgrades and we end up with a level 7 spell with 3 or 4 new attacks and an increased efficiency so it stays at 30 mana.

Amazing story building and character development. The only problem is with the lack of chapters despite the fact that the last update was over 2 years ago. Hopefully it is still ongoing and soon updates.
