The Dangerous Doctor

3 star costume

4 star costume

5 star costume

Class Priest
Role Healer/Buffer
Atk Type Physical
Position Back
Grade ★★★

A doctor whose technique originates from eras with scarce numbers of Priests and Healing Magic. She fires medicine from her large needle to empower allies or weaken the enemy.


Mediana is a healer/buffer specializing in raw attack boosting rather than physical or magical specifically. Her S3 attack buff is the strongest single attack buff in the game, rivaled only by Priscilla. She lacks the ability to shield or CC, but grants a p.crit resist and block to her entire party.

Her S2 is similar to Aisha's beam except much wider, allowing it to easily hit the entire enemy team and her own team. Ironically this makes her a better PvP DPS than most actual DPS heroes.

  • Item introduction: The story goes back to when Mediana's poison experiments were still being kept secret from her peers. One day, a fellow doctor noticed the giant syringe she had made. Impressed by its sheer size, he asked her: 'Look at the size of that thing. Should't you at least give it a name?' To this, Mediana replied, nonchalantly: 'Oh...just call it... Piston.'

  • Item Introduction: A special potion that has two types of effects. Mediana wondered if there was a way to handle attack and recovery at once. She went to the library and read a dusty book called 'Slimes Can Also Make Cannons'. Mediana was reading just for fun, but found a way to apply the principle of cannons into her piston. She was then able to invent the Special Potion of Double Reaction and maximize recovery and attack when using Special Water Cannon. Mediana is still thankful of the author of the book who gave her the inspiration.

  • Soul Weapon Story: Phistonia, Mediana's unique gigantic syringe, has contained many different samples and antibodies from the past experiments. Because Phistonia had once contained the blood of Demons, Dragons, and even demonic beasts, the remains of that power from those fluids started forming a maelstrom of power within Phistonia. It got to the point where even Mediana, who had limited knowledge on otherworldly power, could feel that there's something wrong. And when she finally combined these samples from things that cannot be named to make an antibody, it started to shine brightly. Mediana pushed the antibody into Phistonia, and at that moment, a vortex of power exploded. The mixture inside Phistonia went through evaporation, and an energy in the purest form was born. A soul to succeed Mediana's will to experiment and research, had awakened.

Story from Patch Notes:

Nowadays most people do not deny the existence of Goddess Lua, however, there weren’t many followers before the demons came to the world. Since there were not many priests those who were capable of healing magic when people were sick or injured. By that time, there were some people who were studying and inventing home remedies and chemical remedies, and those people were called ‘Doctors’.

Many years later, after the Holy Sword Aea has shown up its existence in the world, the number of Lua followers started to increase rapidly. Despite there was a huge advance on the medical technology, doctors could not heal people as much as the healers. However, people still believed in doctors.

Mediana was one of them, but her companions have turned their back on her. She was a gifted doctor, but she started to study and invent various types of poisons. Well, there were some rumors going around of course. She has never tested her poison on any living things.

No matter what other people said about her, she seemed she did not care that much. She was joyful only when she got her experiment results. When she heard the news about demons, that was the perfect moment for her to test her studies. She grabbed her needle and she couldn’t hide her excitement.

“Finally…. I can prove myself.”

Hero's Backstory

A practitioner of the medical arts developed when priests where short in supply. She inherited her natural medical talent from her father, but her thirst for knowledge crossed the line when she began researching poison. As a result, she was excommunicated from medical society, but her enthusiasm for research was seemingly unaffected. However, her basic respect for life kept her from achieving any experimental results for her poison research. When the demons appeared, she became overjoyed at finding rare and precious test subjects.
