Instructions
Begin the game, and defeat as many enemies as you can when you are in control of Bowser. As you defeat enemies, you will gain experience points and your experience level will climb. The number of experience points you need to gain a level will increase as your level increases, allowing you to progress and defeat the more powerful enemies that appear later in the game. As long as you progress through the game normally, your level will increase at a constant rate.
Reach experience level 10 to achieve the "Silver Boss" rank. With this rank, Bowser will be able to equip two pieces of equipment at once, increasing his battle stats.
Reach experience level 20 to achieve the "Gold Boss" rank. Bowser can now equip three pieces of equipment at once.
Reach experience level 40 to achieve the "Final Boss" rank and automatically obtain the "Intruder Fangs." These fangs will allow Bowser to perform the same action twice in battle.
