CRISIS CORE –FINAL FANTASY VII– REUNION Buster Sword Proficiency Guide

1: Go into mission 1-2-1 “Challenge from Security” and grind encounters. You can run back and forth between them pretty fast and really get through encounters quick this way. While doing this you must do these three things during encounters.

1a: Defeat enemies while in the Battle Stance with the Strong Attack
1b: Defeat enemies while in the Battle Stance with a Command Materia attack (I recommend Assault Twister)
1c: Go into Battle stance and and take damage until your proficiency stops going up in that fight with Enhanced Guard. Simply going into Battle Stance activates Enhanced Guard so it’s just taking damage.

[[h1]b]Some things you should know about gaining proficiency in encounters[/b][/h1]

2a: You can only earn 30% proficiency for doing each of these things in Battle Stance to make a total of 90%
2b: How much you get per fight is different from encounter to encounter. Usually between 0.05 – 0.12% if my memory serves me right.
2c: You get different abilities at different percentages, but I don’t think there’s a way to see what those are in game. the reason I recommend grinding out the initial 90% first is because you need a piercing ability to get the last 10%. And you get that around 50% of the way through. It just helped me to do one thing at a time to know what I had left to do.

After you get to 90% you will NOT be able to progress without defeating enemies with Barrier and MBarrier while in Battle Stance. I recommend being in New Game + to progress past this point.

The best way to do this is going into mission 9-6-5 “Life-Form of Energy” and grind out encounters because almost all of the encounters have enemies with Barrier and MBarrier. All you need to do is kill enough enemies with Barrier and MBarrier respectively While in Battle Stance to get the last two 5%. It doesn’t show you the progression, it just tells you that you got it with a pop up on the side. It really is just hitting your head against the wall killing enemies over and over. Eventually those screens will pop up. and you will get to 95% and then 100% once you’ve completed each. And again, complete the mission if you want to complete and keep your progress.

Again, 9-6-5 if you’re doing this on a first playthrough is painful! I really do recommend doing this part on New Game + when you would have better gear. But it is possible even if it’s painful. It’s just an end game mission for end game rewards.
