Sona uses the stance mechanic. Her basic abilities all have a persistent aura effect which remains for as long as she doesn't activate another ability. Additionally, her auras remain for 1 additional second after changing stances. Each ability also has an activation effect upon being cast. Sona's basic abilities also set off a 0.5 second cooldown to the other two basic abilities.
After casting 3 spells, Sona's next attack deals extra 8 + (10 × level) magic damage. This enhanced attack has an additional effect depending on which spell was cast last.
