1.1. A 6*6 Expert Caldron with effect 'Rotate'

1.2. Some traits
a) Super Quality = Pro Perfection x Well Made
b) Pro Perfection = Quality Up + x Quality Up ++
c) Quality Up ++
d) Jumbo Size
e) Size +

1.3. Some large size(>=5) gathering materials

1.4. Full alchemy level

1.5. All the recipes

1.6. A lot of Money for dunplication

1.7. Your patience

2.1. With Expert Caldron, filling one grid means +3 quality

2.2. Fullfilling the caldron will give you another 20% quality bonus based on the sum of average quality of materials and grid quality bonus., no matter the caldron's size is.

2.3. The product's size is the average size of all the materials(rounded to the nearest integer)

2.4. Four materials of 9-size can easily fullfill a 6*6 caldron

2.5. If something is 999-quality and 9-size, I will call it a 999-9 thing

2.6. The general ideas are:
a) Try your best to fullfill the caldron
b) Your target is 999-9
c) Fix the trait 'Super Quality', and then set quality up traits if it lacks quality, or size up traits if it lacks size

2.7. I will only list some key materials. I think you can synthesis other 999-9 things with them by yourself.

You can get clay, elixir, neutralizer

This is the easiest cycle:
a) Synthesize Alchemic Clay with quality up or size up traits
b) Duplicate it
c) Synthesize Neutralizer Y with Alchemic Clay
d) Synthesize a better Alchemic Clay with Alchemic Clay and Neutralizer Y
e) Loop util you get 999-9 Alchemic Clay and Neutralizer Y

I recommend you to prepare 3 kinds of 999-9 Alchemic Clay:
a) Super Quality, Pro Perfection, Quality Up ++
b) Super Quality, Pro Perfection, Jumbo Size
c) Super Quality, Jumbo Size, Size +

You can get water, ore, fuel, metal

This cycle is a bit difficult, because it needs more gathering materials of large size.

a) Synthesize Dusk Drop with 999-9 Neutralizer Y, ensure 9-size

b) Duplicate the 9-size Dusk Drop

c) Synthesize Neutralizer Y with 999-9 Alchemic Clay and 9-size Dusk Drop, get a 999-9 product with 3 quality up traits

d) Synthesize Apcol with Dusk Drop, ensure 9-size

e) Duplicate the 9-size Apcol

f) Synthesize Mineral Extract with 9-size Apcol, 9-size Dusk Drop and 999-9 Neutralizer Y with 3 quality up traits. Maybe you can get 999-9 Mineral Extract here. If not, duplicate this and remake a better Dusk Drop

g) Duplicate 999-9 Mineral Extract

h) Remake a better Apcol with 999-9 Mineral Extract. The product should around 500-9. This is used to make a 999-9 Mineral Extract without any quality up or size up traits

i) Remake a better Dusk Drop with 999-9 Mineral Extract and 999-9 Neutralizer Y. Among the gathering materials (1 Suspicious Liquid and 2 Fairy Poison Grass), you need over 15-size and over 360-quality in total to get a 999-9 product. If it is difficult, ensure 9-size first, and the 900-9 product is OK.

You can get fuel, gunpowder

a) Synthesize 999-9 Zettel with 999-9 Mineral Extract and 999-9 Neutralizer Y

b) Synthesize Ramel Flour with 999-9 Dusk Drop and 999-9 Zettel. Ensure 9-size, and the product shoult be over 700-9

c) Synthesize Flame Powder with 700-9 Ramel Flour and 999-9 Neutralizer Y. Among the gathering materials (3 Kaen Stone and 1 Black Orb), you need one 4-size and one 5-size Kaen Stone to build up a 3*3 square, and the last one Kaen Stone and one Black Orb should be over 10-size in total. Ensure 9-size product, and if you can't get 999-9, just duplicate it and remake Flame Powder with Flame Powder.

You can get water, secret power, fuel, neutralizer

a) Synthesize Pure Water with 999-9 Mineral Extract and 900-9 Dusk Drop. Ensure 9-size, and the product should be over 800-9.

b) Synthesize Spirit Tears with 800-9 Pure Water and 999-9 Neutralizer Y. Among the gathering materials(2 Silver Crystal and 2 Crystal Shard), you need over 21-size and 900-quality in total to get 999-9. 999-Quality is difficult, so ensure 9-size and get the product over 700-9.

c) Synthesize Sun Drop with 900-9 Dusk Drop and 700-9 Spirit Tears. Sun Powder over 90 quality is OK.

You can get metal, gem

a) Synthesize Snowflake Crystal with 999-9 Mineral Extract and 999-9 Sun Drop

You can get metal, thread

a) Synthesize Golden Thread with 999-9 Mineral and 999-9 Zettel

You can get animal, gunpowder, elixir, neutralizer

You can get metal, elixir, secret power

a) Synthesize Alchemic Clay with 9-size materals, and wait to the time up when synthesizing, then you will get a 9-size Failure Ash.

b) Synthesize Philosopher Stone with 999-9 Crimson Stone, 9-size Failure Ash, 999-9 Alchemic Clay, 999-9 Snowflake Crystal. Maybe you need 3 quality up traits.
