Even without doing that this game is dead easy.
Step 1: draw 100 of every spell you can
Step 2: Junction those 100 spells to your stats
Step 3: Learn more stat junction abilities
Step 4: Learn the refinement abilities that let you refine spells from items and more powerful spells from weaker ones
Congratulations, you just broke the battle system. And you haven't even learned encounter none and spent time drawing from the islands closest to Heaven and Hell yet.
