"in-depth crystalization guide"

What is Crystallization?

• It's another form of Diamond/Spar which never existed in EWLO except it's way stronger and once socketed it can't be remove by neither of the Small Tier Plier nor Tier Plier.
  
  
  

Can I use it on my Weapon / Equipment / IM's?

• It uses the same rules as Diamond , Spar & Bomb Diamond so as long as you apply the rules, you will know whether or not it's socketable. 
  

Are the Crystal tradable?

• No, only the cards can be traded.

There are 4 different types of Crystal that exist in the game,

1. Chaos Crystal 混沌结晶 [+6, 50% success rate, increases up to +96]. (*6 Chaos Crystal obtainable from Bronze Chicken Card  & Pure Bronze Card )


2. Shadow Chaos Crystal 影混沌結晶 [+6, 50% success rate, doesn't drop if fail, Increases up to +96]. (*3 Shadow Chaos Crystal obtainable from Silver Chicken Card & Pure Silver Card )


3. Pure Chaos Crystal 真混沌结晶 [+6, 100% success rate, increases up to +96]. (*5 Pure Chaos Crystal obtainable from Golden Chicken Card & Pure Golden Card )


4. Pink Crystal 極限魔導石 [+6, 50% success rate, used after +96 increases up to +192]. (*5 Pink Crystal obtainable from Golden Chicken Card & Pure Golden Card )

How much does it cost to make a gear +96?

• It will cost roughly ≥ $12 if you were to socket 1 Chaos Crystal (Use Chaos Crystal first to get a +6) which you get at the start of the game and any 3 of the Gold Card (Exchange for Pure Chaos Crystal) I mentioned above.
• The Golden Card I mentioned comes with *5 Pure Chaos Crystal with 3 Golden Card, you will have *15 Pure Chaos Crystal that will give you +90 and the remainder +6 from Chaos Crystal which you will have to use first as it is only a 50% success rate.
  

Success rate of increasing it to +192?

• The success rate of you getting it to that point is dogshit, I highly suggest you to stop at +96 if you plan on doing it. You may consider increasing it up to 120/126 if your team is settled. (I do not recommend it.)

How much are the card?

• Golden Card are roughly ≤ $4 / ≥ 120,000,000g
• Silver Card are roughly ≤ $2 
• Bronze Card are roughly ≤ $1.5 
  

Is it worth it?

• Go for it if you have the money to buy it for your team if not, don't bother. For context, a set of +52 cost ≥ $8 and a piece of +96 cost ≥ $12.
