If you know where Death is hidden, do not open the container. Instead, use a potion nearby and you should hear Death scream. Open the chest or barrel for a fruit.
Death will die when it takes 100 HP or is hit with a potion.
Stop time and explore
Reach the first end Boss and have a "Stop Time" item. As you are about to die vs. the Dragon, turn on the "Stop Time" item. Make sure it is still running when you lose the life. Choose to continue, and enter any level besides a Boss level. Then, time will be stopped in all levels, monsters will not regenerate, and nothing except poisoned food will harm your character. You will also have free reign on any item, however you will gain hardly any experience points.
