Boktai 2: Solar Boy Django Cheats

If you go into the smithy, you can forge without any sunlight at all. Simply get in talking position so you can talk to Smith. Then, use the Rising Sun magic, and quickly talk to Smith before the shot explodes. Proceed with the forging. Afterwards, if you did it correctly, you will have the same amount of energy you started with. This way, at night, if you want to forge more than once, you no longer need to buy Solar Nuts to restore lost energy.
