Eventually, you have to face the darkness in your heart. However, that doesn't mean you have to do it alone. Time to Dive into the Heart.

This is a video was originally going to be a showcase of a code that lets you force the Riku Ally to cast Dark Aura freely, but then I got really damn creative and motivated. Anyways, for the Dark Aura code, you have to change one of the lines to Riku's pointer address (which is what you use in target mods). You have to use the attack command while locked on to a target for Dark Aura to target properly.

I got REALLY lucky I didn't die in this fight, multiple times. At one point, Roxas's white screen of death glitch happened, but I somehow didn't die before getting to use the Session limit. I figured since it makes the screen go white, it would fix the glitch, and it somehow did. However, I didn't want you all to sit and look at a white screen for 30 seconds, but I didn't want to restart the fight after how amazing it had become. So, if you notice the edit, that's why it is there.

When using the code, you can't use Trinity limit or Limit Form's Limits, because this temporarily removes Riku from the battlefield, thereby changing his pointer address.
