In the Spiny Mole's tunnel in Nova there is a small "X" on the wall when you first enter the tunnel. When you first visit, this has no significance. However, when you return to the "X" after visiting Shadra the "X" will now be a hole that leads to Glissina Cave. In Glissina Cave, you must fight your way through many battles to the final floor. Once there you get an item that helps you defeat Master Macadameus. Note: You cannot enter Glissina Cave if you have already defeated Shadra's first form.
Note: This requires two DS systems and two copies of the game start tag mode. Select a saved game file and exchange to get an Amigo. For more Amigos, start new saved game file in an empty slot, enter Tag mode, exchange, and repeat. Turn in the corresponding number of Amigos in Tag mode to get the corresponding bonus:

Each time you level up, 100 experience points are needed. This is helpful because if you are very weak (at a low level) you will earn a lot more experience points. Note - Try training somewhere you think is best for your level. If your level is high, try Capsicum Caverns on Razen, the fire planet. If you are at a low level try the woods on Gren, the wood planet. Keep in mind that the maximum level is 99.
