Easy Red Orbs in Mission 7: The She-Viper Use the following trick to get approximately 4,300 Red Orbs in about twenty seconds. At the start of the mission, destroy the rocks to your left. Enter the tunnel, and destroy the rocks. You will see the big red crystal near the Secret Mission. In order to get the most Orbs, start with the Stinger, then immediately activate Devil Trigger mode, and quickly mash away. Then, pause the game, select "Systems", and choose "Retry Mission". This is the easiest way to get a lot of Red Orbs in a short amount of time.

Defeating Berial Use Grim Grip to reel yourself close to his head, and attack with your sword. Once the combos are done, use Grim Grip while still in the air. When his flames are gone, jump up to his head. Grab his head with the Devil Bringer, then once he lands from that, use Devil Bringer again to throw and punch him. Then, run a short distance away because he will release an explosion around him. Make sure to pick up Green Orbs from the destroyed buildings, and roll to avoid his flame geysers and sword attack. Continue attacking this way, and use your Charge Shot to defeat him in under a minute.

Defeating Blitzes Use the following trick to defeat a Blitz with Nero. To lower the Blitz "electricity shield" quickly, use charged pistol shots with Devil Trigger mode activated. Charge a shot. Activate Devil Trigger mode. Release the shot, maybe a few more. Turn off Devil Trigger mode, and repeat. This will quickly give you Super Smokin Stylish before he has even dropped his shield. This will work even with a level 1 Charge Shot, but is much easier if you have level 3. Once his shield is gone, use Devil Trigger mode again. Use the Devil Bringer to devastate him. Three throws should be enough to send him into "red mode". Once he goes red, he will try to grab you and kill himself to seriously drain your life or kill you. Shoot normal shots at him to get more Smokin Stylish points and defeat him.
Use the following trick to defeat a Blitz with Dante. Use the Royal Guard style along with the Gilgamesh gauntlets. While the Blitz is in his yellow "electricity shield" state, get close to him and press [Melee] + [Style] repeatedly and quickly. You will be performing a punch and canceling it with a Royal Block very quickly. Think of the [Style] move as the attack. Try to constantly use [Melee] + [Style] repeatedly. You will raise the letter grade of your style meter with each hit, and quickly lower the electric shielding. You are basically hitting the shield yourself, then blocking that hit so fast that you cannot see it happen. Again, just press [Melee] + [Style] at the same time. This may be somewhat tricky at first, but eventually becomes easy. Once his shield is lowered, quickly switch to swordmaster style. Use Real Impact uppercut with the Gilgamesh gauntlets at least twice. Perform a Kick 13 if time permits, and/or a Shocking. He will go into his overdriven "Red Mode". Quickly switch to Lucifer, and perform Bondage. If done correctly, you should defeat him and get a huge stylish ranking from one Blitz.

Defeating Demonic Bosses You can use Nero's Devil Bringer to defeat Demonic Bosses. Before you daze any demonic Boss, get your Devil Trigger as high as possible. As soon as the enemy is dazed, activate Devil Trigger mode, and use the uppercut on them. Using it in different areas of the enemy's body results in a good combo.

Defeating Sanctus Do the following to defeat Sanctus inside of Sparda in Mission 20. While Sanctus is airborne in his shield, get close and break it with sword attacks just like earlier in the game. However, he will sometimes block with the Sword of Sparda. When he does this, use the uppercut technique to break his guard. If you are skilled, you should use the Devil Trigger while he is in the air to use a special combo to force him to the ground. If you fail to do the air combo, just let him fall to the ground. You may be able to get a few sword-based shots in, but do not try to rely on this because he may escape. At this point, use the uppercut in Devil Trigger mode, if possible. Afterwards, he will go back to being airborne again, in which case you should not use the Devil Trigger. After you have gotten his health down to around 10% to 15%, he will use a charging sword attack (however, if you have perfected the aforementioned combo, you may bypass this). Defeating him requires timing. At precisely the correct moment of his charge towards you, uppercut to break his guard. Again, as soon as it is broken, Devil Trigger uppercut to finish him off. In the second battle against Sanctus, as the False Prophet, timing is once again crucial. All you must do is uppercut his attacks away.
