Aura:Sona's basic abilities each generate a unique aura for 3 seconds that empowers her and all allied champions who enter its radius, also incurring a 0.5 seconds period during which she cannot cast her other basic abilities.
Power Chord: After casting 3 basic abilities, Sona's next basic attack deals 20 − 240 (based on level)(+ 20% AP)bonus magic damage, with an additional effect depending on the last basic ability cast.
Power Chord resets Sona's basic attack timer.
When Power Chord is ready, Sona gains a ring around her.
This ring will have a different color depending on the last ability used (blue, green or purple).
The effect does not change if abilities are used while the projectile is in motion.
Sona's auras will only affect allied champions, not minions or pets.
