In the game Epoch of Stars, although some heroes do not have outstanding combat power, their support abilities are quite excellent. They can use their own skills to provide buffs that increase damage or reduce damage, and some can provide healing abilities, which are quite powerful throughout the entire battle. Therefore, people often ask what the healing skills in Epoch of Stars are? Here, I will provide some useful healing skills.

Firstly, there is the Oxygen Supply Device, which is an A-grade active skill. However, the active effect of this skill can only heal itself and restore a certain amount of durability, mainly enhancing its own ability. It is more suitable for use with some main characters. Additionally, when this skill is activated, there is a certain probability that it will cause three enemy units to overload, preventing them from performing rapid shots, thus stopping the enemy from dealing burst damage.
Next is the Gene Chain, which is a probabilistic team recovery skill. During 10 seconds of battle, it can restore the health of itself and two friendly units, but the probability is only around 55%. Sometimes, if it does not trigger during battle, it can be very detrimental. Therefore, it is better placed on support roles, especially those that enhance damage, as they can carry such a probabilistic recovery skill.
Then there is the Cardiotonic, which is a healing skill for damage dealers. There is a certain probability that its normal attack will turn into a rapid shot, which increases damage for a short period and restores a certain amount of health to itself. This is more suitable for backline damage dealer roles in our team. This skill can actually be seen as a probability-based lifesteal and is not very suitable for support roles.

Following that is the Radiant Light, which is a standard area-of-effect healing skill. With almost a 100% chance of healing five units, this greatly improves the team's sustainability. It is very suitable for any support role, though it is even more fitting for those that lean towards healing.

Finally, there is the Undying Spirit, a skill for tanks. Since this skill only heals when parrying, it is very useful for tanks without self-healing capabilities, significantly increasing their durability.

Currently, these are all the details I've provided about the healing skills in Epoch of Stars. Healing skills have many uses, but they need to be paired based on their characteristics. Among support-type heroes, Radiant Light and Gene Chain are recommended.
