Dr. Ratio’s gameplay

Dr. Ratio is destined to be a DPS since his abilities are tailored to deal single-target damage to enemies. Further details about his gameplay have been listed below:

• Basic ATK: Inflicts Imaginary DMG on a target.
• Skill: Deals his ATK as Imaginary DMG on a single enemy. It further triggers an effect from his Talent depending on the number of debuffs inflicted on enemies and deals enhanced damage to them.
• Ultimate: Unleashes Imaginary DMG on an opponent and gains a buff, which increases the chance to trigger follow-up attacks from his Talent. The effect stacks up to two times, and the trigger count resets after Dr. Ratio casts his Ultimate.
• Talent: Randomly gains a buff, which launches a follow-up attack scaling on his ATK stat. The buff can also increase either his ATK, CRIT Rate, CRIT DMG, or SPD for a total of three stacks, lasting for three turns.
• Technique: Upon casting, it creates a special dimension that Taunts nearby enemies. Dr. Ratio can further reduce the SPD of the opponents within the area after entering the battle.
