Inside of Nohl's hospital (the large house you start in), go to the far right of the house. Inside the drawer in Hawke's room is the Point Card, with unlimited attacking power.

Remain idle for one minute at the title screen. A special effects scene will start.

Immediately after you get to the town of Darakin Citadel and are able to go outside on the main world map, Go back to your home town of Nohl. Talk to Maxwell, the man standing in front of a building to the left of the item shop. He will challenge you to a game of "Sidejump". Play this mini-game, and every time you get the high score you will get a Heal Potion. Every time you defeat him, you get a Heal Leaf. You can play and defeat him as many times as desired. Maxwell only gets a count of 20 jumps, so if you get 21 you will get a Heal Potion. If you beat your high score by 1 (22 jumps), you will get another Heal Potion. Beat your score by 1 jump each time and you can get about 20 Heal Potions. After you beat you high score as many times as you can, every time you play against Maxwell and beat him, you will get a Heal Leaf.
