Skills are effects that can be triggered while playing a Live. There are three categories of skills:
- Active (アクティブ): Bromides in the Member row have a chance to activate these skills for a certain amount of time.
- Passive (パッシブ): Bromides in the Member row activate these skills at the start of a Live.
- Support (サポート): Bromides in the Support row provide additional stat increases to the corresponding bromide in the Member row.
All bromides have Active and Support skills, but not all will have a Passive skill.
Skills can be leveled up through the Strengthen screen on the Members page. Skills are initially Lv.1 but can be increased to Lv.10. As the skill is leveled, the stat bonuses they provide also increase.
The rarity of the bromide also determines how strong its skills are. Bromides may have similar skills, but their effects will be stronger the higher the rarity. This is designated by the number of "+" the skill has next to its name. When a bromide is awakened, all of the bromide's skills gain an additional "+." For example, an SSR bromide may only have Score UP ++ which grants a 28% score bonus at Lv.10, but when it is awakened to a UR, the skill becomes Score UP +++ which grants 33% at Lv.10.
During a Live, once the song hits the chorus it enters FEVER mode. You can tell when this occurs when your bands' bromides appear on the screen and your myumon audience are holding penlights. During FEVER mode, the skill activation rate is increased. Being aware of the note attributes can also contribute to higher scores. If specific attribute notes are concentrated during a FEVER, it can be easier to earn a higher score.
