Power Chord
Innate - Accelerando: Sona generates a stack of Accelerando each time she hits an enemy champion with Hymn of Valor and each time she mitigates sufficient damage or heals damaged allies with Aria of Perseverance, stacking up to 120 times. At maximum stacks, she instead reduces the current cooldown of Crescendo by 1.5 seconds each time. Accelerando: For each stack, Sona gains 0.5 basic ability haste, up to 60 at maximum stacks.
Innate - Melody: Whenever Sona casts a basic ability, her other basic abilities incur a 0.5-second global cooldown and she generates a unique aura for 3 seconds that empowers herself and nearby allied champions. Only one aura can be active at a time.
Innate - Power Chord: Sona's basic abilities generate a stack of Power Chord, stacking up to 3 times. At 3 stacks, her next basic attack is empowered to consume them all to have an uncancellable windup, deal 20 – 270 (based on level) (+ 20% AP) bonus magic damage, and apply an additional effect based on the last basic ability she cast: Hymn of Valor - Staccato: Bonus damage is modified to 30 – 405 (based on level) (+ 30% AP). Aria of Perseverance - Diminuendo: Reduces the target's size by 8% and damage dealt by 25% (+ 4% per 100 AP) for 3 seconds. Song of Celerity - Tempo: Slows the target by 50% (+ 4% per 100 AP) for 2 seconds, capped at 99%.
Gaining Power Chord's empowered attack resets Sona's basic attack timer.
