ACTIVE: Seraphine empowers herself and nearby allied champions with her music. She grants herself 20% (+ 4% per 100 AP) decaying bonus movement speed and a 75 − 225 (based on level) (+ 45% AP) shield for 2.5 seconds. Allies are granted 8% (+ 1.6% per 100 AP) bonus movement speed and a 50 − 150 (based on level) (+ 30% AP) shield for 2.5 seconds.
Surround Sound will also heal Seraphine and all nearby allied champions for 5% (+ 1.125% per 100 AP) of missing health per ally after its effect ends if Seraphine already had a shield at the time of cast.
Surround Sound's effects can stack up to 2 times.
