If you want to become an owerpowered character i recommend firstly to change upgrade points and then manually put them into abbilities during the game. This way you will activate all tutorials properly.

After that set this values (i used them):

[fireAbilities]
smokeBomb="30"
[waterAbilities]
ice="10"
[earthAbilities]
vineCapture="15"
entanglingVines="30"
[spiritAbilities]
embraceRange="50"
throwDistance="50"
throwPrediction="50"

I suggest to keep some charms not gained so you could find them on the levels and check task.
