0-1 star: 1 0-star** card is used as a secondary card, the success rate is 100%. Everyone knows this and I won’t say more;

1-2 star : Use a 0-star ** card as a secondary card, with a success rate of 72%. However, when synthesizing in large quantities, it is recommended to use a 0-star medium card as a secondary card. An 80% success rate can significantly reduce losses;

2-3 stars: 1 0-star good card as secondary card, level 1 four-leaf clover as assist, success rate 73%. I want to say something here, if you are just making a small fuss, just use 1 0-star card** Cards can be used to achieve 3 stars, with a probability of 48%, but it is not recommended for large-scale synthesis, and newcomers do not have too many materials to try;

3-4 stars: 1 2-star good card + Two 1-star mid-level cards are used as secondary cards, with a level 1 four-leaf clover as an assistant, and the success rate is 94%. Originally, to go to 4, you can use 1 2-star good card + level 2 grass, and the success rate is 75%, but considering the increase in level 2 grass price, the matching success rate of 211 is very high and the cost is similar, suitable for large-scale synthesis;

4-5 stars: 1 3-star good card + 2 2-star medium cards, level 2 four-leaf Grass assist, the success rate is 77%. There is no need to directly gamble with the 56% chance of 3-star good cards + level 2 grass. You will know when you strengthen many cards;

5-6 stars: 1 A 4-star card + 2 3-star cards + level 3 grass, a 78% success rate can effectively control your losses. The comparison group is 2 4-star cards + 1 3-star card + level 2 four-leaf clover, a 71% success rate , the probability is relatively stable around 70. If it is lower than 70, the possibility of continuous explosions increases sharply; there is another one, a 3! Bring nothing but a 3!

(From below, due to the reduction in the success rate of enhancement, all secondary cards used are good cards. The main card will not be repeated if the enhancement fails. The main card will drop 1 level. You can spend 500D to purchase amulets to protect the main card from falling. Level) to add personal experience:

6-7 stars: 3 5-star good cards + level 3 four-leaf clover, the success rate is 74%. This is a hurdle. It is not recommended for everyone to use amulets when reaching level 7. , but 74% is not a very high or safe number. What should we do? Don't worry, followme, first strengthen several 1-star cards and 0-star** cards, the success rate of rushing to 2 is 72%, be bold, if you blast twice in a row and then rush to 7, you can basically succeed;

7-8 stars: (The amulet must be placed, otherwise you will understand the consequences) There are 2 options, 1.3 6-star good cards + level 4 four-leaf clover, the success rate is 70%, this kind of card padding method please Referring to 6-7 stars; 2.1 6-star good cards + 2 5-star good cards + level 3 four-leaf clover, the success rate is 51%. What should we do in this situation? First, strengthen several 2-star cards and 0-star medium cards. The success rate of reaching 3 is exactly 51%. Try a few more times. When it explodes about 4 times in a row, go for 8. Maybe there is something to say, but I still failed. , look at how many points you save with your 655+3-level grass compared with others’ 666+4-level grass? Risks and opportunities are directly proportional;

8-9 stars: (Who dares not to put a protective charm?) There are 2 options: 1.1 7-star cards + 2 6-star cards + level 4 four leaves Grass, the success rate is 49%, please refer to the second plan of 7-8 stars for padding; 2.3 6-star + level 3 four-leaf clovers, the success rate is 30%, a bit low, right? There is no way, look at you How much corners were cut? But can it succeed? The answer is yes, I did it 3 times. First prepare dozens of 3-star cards and 1-star** cards. The success rate of rushing to 4 is 32%. Click on it and slowly figure out the rules. Generally, you can see the trick after 20 times. For example, 6 failures become one, etc. Okay, next time you fail 6 times, go to 9 boldly. Remember to prepare two sets of materials.
