Friends, do you know how to use the Bloody Revenge Doctor skill? Today I will explain the tutorial guide on how to use the Bloody Revenge Doctor skill. If you are interested, come and take a look with me. I hope it can help you.

The doctor has his own active skill of applying medicine, which can be used once on each teammate except himself to +25 health in each level.

​ ​ 1. As a doctor, you must remember which teammates have applied medicine and which ones have not. This allows for better planning of blood volume and use of medicines and props.

2. When clearing a level, remember to use up the medicine and it cannot be accumulated to the next level.

3. If your teammates are just short of a little blood, don’t use it. For a fixed +25 it's a waste.

4. Don’t wait until it is above 25 before using it. Just use it when it is almost +. If your teammates see that you are too lazy to add blood to it, it will easily break.

​ 5. This application of medicine and blood can enjoy the effect of the treatment effect bonus card. At the same time, if a teammate dies once and is resurrected, the medicine will be refreshed and you can apply it to him again. Then it seems that if the doctor dies once and is resurrected, he can apply it again to the entire team.
