This is pretty simplistic for an Arachne battle. You'll dealing with 2 separate waves of 2 Arachne, and that means no DT'd enemies (unless you're really bad of course). So, the key to successful Arachne battles is the audio cue - EVERY attack they do has a hint. When you hear one, jump + Air Hike, then release a barrage of Multi-lock. Always fight one enemy at a time and to remember keep track of the other one while fighting him. You hear a sound, you jump, hike, and release.

Constant hitting on an Arachne can eventually cause it to stagger, and when it does, it is TOTALLY vulnerable against knockbacks and juggles. Hightime the Arachne (not Rising Dragon) and you can quite successfully do a K Bee rebound barrage on it. Be VERY careful when taunting Arachnes. It is far more dangerous than other normal enemies. If possible, end this fight with DT remaining.

Note: At Sub Ground Water Vein, switch to Quicksilver and run past the first group of Enigmas. Once they're out of sight, you can pretty much dodge your way past the final one without too much hassle.

This is pretty simple in all. Avoid ALL the revolving blades (walk slowly if you must) and run in between each one in time with the Enigma arrows or alternatively, give him a few long distance Spiral shots. Once half way through, hide behind the wall so the 1st Enigma doesn't hit you and shoot with Spiral to knock him down (hide when he shoots). After he's down, stroll on to the second Enigma and knock him down with Spiral, then either do Sniper or Multi-lock to finish him off. Remember to taunt, then proceed to Provisions Storeroom 2.

The first part of this battle is the same as the first Arachne battle. Always keep check of both enemies and target one first. KEEP it locked on and never release it as you're killing each target. After the first 2, you're in for a tougher fight - 3 Arachne at once. The logic stays the same - target one and attack immediately. Use DT (not DTE) to kill faster but don't get carried away. If you hear an attack, Air Hike and shoot. Once he's dead, target any other and do the same. The last enemy will DT but as long as you keep check and don't do anything stupid, Artemis multi-lock will keep your style ranking high enough.

Set up - Quicksilver with Spiral + Beowulf

Nevan is surprisingly one of the easier bosses to "No Damage" and attain a good boost to your style meter. Here's what you do.

At the start of the battle, stroll up to her, trigger her Spin attack by walking directly in front of her. When she does her Spin, do a small backflip back and immediately charge a Straight. She will spin 4 times before dropping her arms. THE MOMENT her arms touch her hips, release Straight.

What will happen is that Straight will break her barrier in a single strike, then fire Spiral to knock her onto the floor and do backflip cancelling to inflict maximum damage. (don't DTE or QS at this point). She will now teleport over to the other side of the room. Trigger her spin attack again but this time, DTE (this will also break her barrier, though it must be maximum) and perform any random combo on her (don't K Bee cancel, you'd want to do normal damage). After that, she'll teleport again over to the other side. Repeat the Straight, Spiral and backflip strategy. (Watch your DT fill up, it's fun)

Now, Nevan will go into her second phase, which you'd want to end as quickly as possible. Stay by the steps and wait for her Electric Floor attack. As long as you are on the steps, you won't get hurt (she sometimes does it twice). Stay by the stairs since she has a habit of teleporting there again and you DON'T want that. Wait for her to start her Electric Pillar attack, dodge the first 1 or 2 waves (sometimes she does the Light Pillar attack that emerges from beneath Dante, and this makes things easier) and then stroll up to her and DTE, followed by Back flip Cancelling again.

She'll now be back to her first phase, so stroll to the top of the steps and trigger her Spin. Straight and Back flip Cancel as usual, and do the same DTE thing on the other side of the room. FINALLY, when running back to the top of the steps, trigger Nevan's Spin, (should be significantly longer now) Straight, Spiral AND quickly activate QS and Back flip cancel like an absolute nut-case. If you feel you won't kill her with it, don't do it. Just stick to the DTE + Straight strategy. Quicksilver is really just to end this battle faster and give you added safety with Quick Cancel. This concludes mission 9.

Note: When triggering Nevan's Spin attack, you always have time to taunt before she starts. The extra DT always comes in handy.
