When you first begin the game and are in the room where you first get a weapon and learn how to turn items into Elixir, turn both weapons that you get into Elixir. Because the programmers did not want you to have to start without a weapon, both weapons will re-appear. Collect both weapons again, then turn both of them into Elixir again. Repeat the process as long as desired. Because Elixirs are used to power-up you can make your character as powerful as desired immediately at the start of the game.
