When the SP Gauge is full, the player can trigger an SP Skill, which gives a big score boost and also boosts the score of successful notes for a few seconds. Upon switching, you also get a boost based on a randomly selected idol's type in the Strategy trio that you swapped to. For example, switching to a trio with two Voltage types and one Skill type boosts scoring and skill activation rate at the expense of a quicker Stamina drain. When a switch gauge is full, players can change strategies, which gives a bonus and affects how the group is performing based on the type of the idols in the new Strategy trio. Each group of nine idols is now split into three Strategy trios. Each idol has a Skill much like in SIF and one or two Abilities like a SIF Center Ability – however, in SIFAS, these Abilities are usable even if an idol is not the center. There are also four new different types – Voltage (higher scoring but bigger Stamina drain), SP/Special (SP Gauge charges faster but skills activate less often), Guard (Smaller Stamina drain but SP Gauge charges slower) and Skill (lower scoring per note but skills activate more often). Compared with SIF, there are no individual Appeal, Stamina or Technique stats for each attribute, but matching the attribute to the song attribute still boosts the statistics. In addition to the three previous attributes from the original School Idol Festival, there are three new attributes: Active, Natural and Elegant.
Each idol has three statistics: Appeal (how quickly she can generate Voltage, or score), Stamina (adding to the group's total Stamina) and Technique (how often Critical notes with a 50% score bonus appear – also affects the SP Skill's power if the idol is one of the first three on the roster).As part of the compensation, some idols' skills can generate shields. In a change to the original School Idol Festival, even perfectly timing notes drains at least some stamina.Nurture your idols and aim to clear stages!.More than just a rhythm action game, it features a new live system.
Through the usage of skills, you are able to evolve their performances to create your very own lives. The non-daily songs have full dances, including 2-person, 3-person, 4-person, 9-person, 10-person, and 12-person formation dances in full group songs.
