This is the ‘achievement’ I did not get in my game of playstation version before. With a lot of attempts and adjustment, I finally finished it.

I got the key point from here (it’s a chinese community), and I make some change myself to get a better effect.(such as stats enhancement and traits combination)
http://bbs.a9vg.com/thread-4819985-1-2.html

There is another guide of mine. I’ve already wrote some practical things in it. And here, I will also let you check something in that guide.

2.8. Your patience

I will mark them with UR, SSR, SR, so you can check how to get them in my another guide.(Sounds like a Japanese gacha game, right?)
If the trait’s effect can be affected by quality, I will mark a ‘Q’ there. Obviously, more quality, more power.

3.1. UR:
Dreadful King
All stats (except DMG) +25, 50% additional damage to normal attack and support attack

Pursuit of Knowledge
75% additional damage to normal attack and support attack

Hammer of Justice
+75% skill power and bomb damage

Power of Madness
+100 ATK , consume 50 HP when act every turn

Defenseless Curse (Q)
Powerful DEF debuff

3.2. SSR:
Evolves the Body
Increase base stats by 20%

Power to Destroy Gods
Increase attack item effect by 40%

Guide Intuition (Q)
Increases critical hit rate, has a chance to shorten wait time

3.3. SR:
Awakening Courage
+7% damage against higher level foes, +7% damage against bosses, can be added up to 14% in total

Bonds of Belief (Q)
Increase assist effect, drain HP

Cunning Wit (Q)
Increase accuracy and critical bonus

One Time End
Increase item power by count*10%, but completely consume item in one use during battle

3.4. Others:
Well Rounded Power
All stats (except DMG) +25

Speed of Light
SPD +40

Trait Super Enhance
Enhance item effect according to strength of traits present. Stronger traits equal ridiculously greater enhancement.
The formula is: [(Sum of traits’ level)^0.7+10]%. Trait level is hidden data to players. You can check it in Official Guide Book of Atelier Sophie (Japanese).

One Hit Kill
Always critical and KO target. No KO effect to bosses

Demon Soul
Ignore the introduction in game. The real effect is a 100% magical additional damage.

Power of Faith (Q)
Increase critical hit rate and damage dealt to broken targets.

Ancient Seal
Increase 50% damage against puni and magical creatures

4.1. Ori Bomb plus True Cross Cut
- Fritz’s first skill ‘True Cross Cut’ is one of the most powerful way to deal damage. It says that it can be enhanced by split damage, and Ori Bomb is the best choice. Throw Ori Bomb first and then use True Cross Cut, its damage will be enhanced by about 10k points with my settings.

4.2. Against Tormented Beast
- Tormented Beast has low break resistance and high physical resistance.
- His SPD is about 400. Considering the float, SPD 440 can be faster than him.
- My designed start order is ‘Sophie -> Leon -> Harol -> Fritz -> boss or boss -> Fritz’, which can result in the action order ‘Sophie -> Leon -> Harol -> Fritz -> boss’.
- In battle, Sophie and Leon break the boss first, and then finish the battle with Ori Bomb - True Cross Cut combo.

4.3. Against Shadow of Oblivion
- Shadow of Oblivion has high break resistance, high SPD and low physical resistance.
- I need about 540 SPD to be faster than the boss. That’s hard. So I throw a Lightning Crystal to push the boss to the bottom, and everyone can act faster than him.
- In my party, Sophie needs to act first, Fritz the last, Harol and Plachta between them no matter the order is.
- In battle, Sophie throws Lightning Crystal, Plachta uses normal attack, Harol throws Ori Bomb, Fritz uses True Cross Cut.

4.4. SPD Adjustment
- Action order is important for me. So I use different material to enhance different character's equipment to achieve my designed order.

Sophie’s attack ability is weak, so she just needs to throw bombs.

Then this is my settings of Sophie:
-
Enhance weapon with this:
-
Enhance armor with this:
-
How to do a lossless enhancement and why I choose Time Control Hourglass are introduced in my another guide.
Hustle Belt can enhance the break value of Flame of the End
Bonds of Belief enhances Sophie’s support attack.

Leon is only in formation against Tormented Beast.
Leon’s third skill ‘Ether Rose’ can deal huge break value, that’s the reason I choose her.

Then this is my settings of Leon:
-
Enhance weapon with this:
-
Enhance armor with this:
-
Hourglass plus one Guide Intuition can ensure over 95% critical rate, and two Cunning Wit enhance the critical damage.

Plachta is only in formation against Shadow of Oblivion.

Then this is my settings of Plachta:
-
Enhance weapon with this:
-
Enhance armor with this:
-
Make doll with these:
-
Get the Friendly Persona from Tess in cafe. This is the only one that has 'Demon Soul' on it. This can double Plachta's dealt damage with normal attack. And this is another powerful way to deal huge damage.
When make doll, try to use the 9-size materials if possible. Materials have their own basic enhancing stats. Larger size, more stats. You can check more detail in my another guide.

Harol can enhance bomb's damage with one of his passive skill. I forget the percentage, only remember that it is very powerful. So Harol just throw Ori Bomb to deal damage and deal great split damage for Fritz.

Then this is my settings of Harol:
-
Enhance weapon with this:
-
Enhance armor with this:
-
Hammer of Justice can also enhance bomb's damage.
About White-Hot Headband:
- Inner Fire provides a damage bonus agansit boss
- Inject Warlike Spirit can enhance critical rate and critical damage.

Fritz acts the last with True Cross Cut in both fights.

Then this is my settings of Fritz:
-
Enhance weapon with this:
-
Enhance armor with this:
-
SPD doesn't affect skill damage, so let's ignore it, and completely enhance DMG and ATK.
Even if Fritz is slower than Tormented Beast, he can still act faster than the boss with an unknown SPD bonus because the other party members are fast enough. I don't know why, but that's it.
The second effect of Time Control Hourglass is 'Speed to Power'. It can convert 15% SPD to ATK, a best thing for Fritz, though it is dangerous to others. So I only make it for Fritz.
Power of Faith can enhance the damage when the target is broken. This is only for the fight against Tormented Beast.
XXX Slayer is only actived when using normal attack, so it's not suitable for Fritz.

10.1. Sophie's Bombs
-
Flame of the End is for Tormented Beast
- 4th effect 'Add Break XL' can deal huge break value to the boss
- Defenseless Curse can cause a sharply DEF drop
- Power to Destroy Gods can enhance both bomb damage and break value
- Demon Soul doubles the bomb damage
- With this, I can break Tormented Beast only by Sophie and Leon, and deal a great debuff to boss.

Lightning Crystal is for Shadow of Oblivion
- One Time End and Trait Super Enhance can reach the limit of effect enhancement, so I set the last slot with Defenseless Curse.
- The pushing effect you can see in the video. It's terrible!

10.2. Harol's Bombs
-
These two are only differ from one trait

The 'Demon Soul' version is for Tormented Beast
- Sophie and Leon have already break the boss, so every hit must be critical. One Hit Kill is a waste here, so I set Demon Soul instead to enhance the damage.

The 'One Hit Kill' version is for Shadow of Oblivion
- I can't break the boss, so I ensure a critical hit to get higher damage.

Harol's bomb damage is high enough, so I set two Cunning Wit on his accessories to enhance critical damage.
Guide Intuition does no effect on bombs.

You can check how to make some 999-quality materials here
http://steamproxy.net/sharedfiles/filedetails/?id=871678196

To all use items, larger size means more use times. No bonus below 3-size, and +2 size = +1 use time when over 3-size.

11.1. Ori bomb
All the materials can be synthesized and it's easy to get to 999-quality. You just need to adjust its size, and do not need to fullfill the caldron.
- 999-7 Bomb
- 999-6 Flame Powder *3, color red
- 999-7 Neutralizer R *2, with 3 target traits

11.2. Lightning Crystal

- 999-9 Blitzlite *2, color green
- 999-9 Snowflake Crystal *2, color green
- 999-9 Mineral Extract *2, with 3 target traits

11.3. Flame of the End
Almost to be impossible to get a 999 product withou quality up traits, because alchemy level is not enough and will have a quality loss.
- 999-6 Crimson Stone
- over 300-3 Sun Powder *2, you can get them by farming huge red dragon in DLC map
- 999-6 Flame of Origin *2, with one target trait

5*5 Expert Caldron, fullfill the caldron with all the materials. Adjust the order to limit the second effect.

11.6. Hustle Belt
- 200-3 Animal Fur *2

- 999-5 Golden Thread, with 1 target trait
- 999-8 Crystal Ball
5*5 Ancient Caldron, fullfill the caldron with all the materials. Set the Ingot the last.

About 200-3 Animal Fur:
- You need to farm this monster in DLC map at gathering level 5 (harder difficulty may drop higher quality materials, not sure. If it's hard to defeat, just set EASY)
the purple one
- When get into the battle, you will see the book monsters. Kill all the demons, and wait for the books summoning the beast 'Lightning'.
- Kill it and you will get a high quality Animal Fur of 3-size.
- You need 6 in total. It's a hard work.
