Skills and Center Effects

Skills
Skills (スキル) are present in Idol Photos with a rarity of R or greater and can give special effects. This skill level is capped out at Lv. 5 for un-Changed Idol Photos, while Changed Idol Photos have a skill level cap at Lv. 10.

Skills can be leveled up by using Lesson Notes gained from Lives, Work, and Events.

Producer Skills
Producer Skills (プロデューサースキル), also known as P-Skills, are special skills that get activated by special purple notes during Lives. These can be selected at the unit selection screen before starting a Live, and are selected per unit. Players can gain more Producer Skills as their Producer Level increases.
