Start a new game and choose a Sorcerer or Sorceress. They have the lowest health and can be defeated easier than the other classes. Make sure they are at level 1 with no items equipped. Do not start a new quest; instead choose a quick battle and fight a swarm of rats. The rats will have the first move. With luck, they can do enough damage to kill you in the first turn. Quick battles feature a random grid. You will need to keep cycling through them until you get one that has some +5 Skulls ready to be matched near the bottom. If the CPU matches them, you will lose a large portion or possible all of your health. If the enemy does not attack or you do not die on the first turn, exit and retry.
