-Obtain 4x Mega Flare
-Get your HP down below 25% [Or until you are flashing red]
-Go to Radiant Garden, where you fought Trinity Armor
-Run into the middle of the Glass on the ground, run back to its edge, and cast a Mega Flare. Wait a second, cast a 2nd Mega Flare for the 2nd round of enemies. If the 2nd round does not appear, run back to the middle to get them too. You should make 4-5k per round, using Terra. Using Ven or Aqua with a Mickey D-Link should net you even more.
