Use the Amulet to max out your Levels, HP, and Gold
When you are on the verge of raising a level, use the third and final charge of the Amulet on the monster that would've raised your level. The game will freeze for a second, the screen will flash, and your levels, HP, and gold should max out, along with the message that your Amulet is exhausted of it's powers. YOU MUST USE THE THIRD AND FINAL CHARGE of the Amulet for this trick to work!
This trick will not work in boss fights.
NOTE: This trick does not work on the SNES version of Y's III.
