SOUL ATTACK("INTERMEDIATE" AND "ADVANCED") I'm currently trying to win..

I really didn't find Soul Attack very difficult at all, but I'll see if I still remember how I did it.
1. I used a lvl.175 Final Form Ichigo, so yeah that makes everything easier. In your mission 28 question that I just answered, you said you had many fully upgraded characters, right? Ichigo should be one of them.
2. Final Ichigo has a spirit attack called Kuretsusen that has a long, wide range and moves quickly. You should use this a lot. It easily clears a room of weaker enemies in just a few quick slashes and can even take down a Menos Grande in just a few hits. It can be used while moving to attack bosses to stun them while you walk over to them.
3. When you are close enough to the boss, you can do close range attacks with square. A useful trick is to press X after the final upward slash to instantly rush into the air next to the stunned boss, then use air combo or, even better, Tenburenjin (to utilize the full power and duration of this super move, you have to rapidly press O again and again, much like Yoruichi's Musorenbu and Byakuya's Gokei Senbonzakura Kageyoshi)
4. Final Ichigo's Ignition attack, Mugetsu, is unique in that it is much more powerful than all other Ignition attacks in the game. The darawback is that it drains your own health a lot, but you have three extra lives so you are in no danger at all. I cannot emphasize enough how much time it can save you if used intelligently. In fact, I'll tell you right now that if you use it against Kenpachi, Byakuya, and Final Ichigo at the same time as soon as you enter the final room of Intermediate Mode, you can hit all three bosses if you time it right and that fight won't last five seconds.
Hopefully that's enough advice because I already typed a long response to your mission 28 question today and I need a break, but anyways I always enjoy answering your Bleach Soul Ressurreccion questions because it makes me feel helpful. Good luck, michaelhole137.
