In the world of Rock Kingdom, each type has some rather special skills. These skills can fully leverage the advantages of certain spirits and even turn the tide of battle. The skill "Evil Exchange" is particularly unique, and many newcomers are not quite clear about it, naturally asking: What is the effect of the Evil Exchange skill in Rock Kingdom? Here, I will provide a general description of the Evil Exchange skill's effects.

The Evil Exchange skill actually does not have much damage effect, but its passive effect is very strong. It swaps the proportion of one's own health, making it a skill that can turn the tide of battle. For example, if the opponent is still in a healthy state while you are close to being critically low on health, you can use this skill to swap both parties' health directly. This makes it much easier to defeat the opponent.

At the same time, the Evil Exchange is also suitable for swapping a hero with low health for one with high health. For instance, at the beginning of a match, if the opponent's spirit has significantly more health than yours, then you would be at a disadvantage in the battle. Using Evil Exchange at this point can directly swap the health proportions, turning the disadvantage into an advantage. Of course, it is best to use this skill only once per match, as using it a second time would revert the status back to the original, potentially exacerbating the disadvantage.

However, not all spirits can learn this skill. It is an exclusive skill of the evil type, and generally, only evil type spirits can learn it. Other types of spirits find it extremely difficult to learn. Even if they do, it might conflict with their own mechanisms, making the skill applicable to only a small number of spirits.
Among these, the proportion of evil spirits using Evil Exchange is relatively high. For example, Dragon Breath Pal, who is actually a mini-boss on the map, has a dragon-like appearance and decent strength, appearing mighty and imposing.
This spirit's characteristic is that killing an opponent's spirit directly reduces their magic points by one, which aligns with the characteristics of Evil Exchange. This ensures a solo kill against the opponent, preventing them from using energy skills.

Currently, this is all the information provided about what the effect of the Evil Exchange skill is in Rock Kingdom. The Evil Exchange skill can be used to swap the proportions of both sides, and when there is a significant difference in health, it can have a good effect!
