Prey sacrifice
The game is set to upgrade the gameplay, and every two prey can sacrifice one magic scroll. Sacrifice rules
Rule：
The one with the highest level of the two prey is used as a reference. The prey participating in the sacrifice disappears (the rarity of the prey participating in the sacrifice does not affect the final probability), and there is a certain chance to sacrifice a prey one level higher than the reference prey. The attributes of the five elements are turned on according to the probability of the mutual proportion of rarity, and 1% of the attributes of the other five elements are turned on. Only prey with the same attributes and idle state can be sacrificed.
Note:
When two prey are taken to sacrifice, these two prey will be burned and get a higher level scroll. For example, a 1-star prey and a 1-star prey sacrifice will get a 2-star scroll, and a 1-star prey and 2-star prey sacrifice will get a 3-star scroll. The sacrifice does not require two prey of the same star. The level of the scroll obtained by the sacrifice will be higher than the highest level of the two prey used for the sacrifice.
Probability calculation：
Advanced level | Probability of success | Probability of failing but retaining high-grade one |
1 star - 2 stars | 100% | 0% |
2 stars - 3 stars | 80% | 20% |
3 stars → 4 stars | 50% | 50% |
4 stars → 5 stars | 20% | 80% |
5 stars → 6 stars | 10% | 90% |
6 stars → 7 stars | 5% | 95% |
7 stars → 8 stars | 1% | 99% |
Note: When offering sacrifices, you need to use some skills in the level combination. For example, the probability of using a 1-star+3-star prey to sacrifice to obtain a 4-star scroll is the same as the probability of using a 3-star+3-star prey to sacrifice. Of course, it is more cost-effective to choose 3 stars + lower-level prey to sacrifice 4 stars.
