I already knew about the bottles, but thank you for your adviceIf you really want to break the game, you can just save scum for every loot chest (save, open chest, check, if not best gear: load and repeat).
Grind a tad until you're about lv. 25, then repeat the save scumming for best gear.
Now you'll one hit pretty much anything.
And while you're at it:
Make use of the infinite empty bottles (in your cellar) + water (well in front of your house) supply.
That way you can always replenish your MP between fights w/o any cost.
