Activating Sona's basic abilities creates a unique 350-radius aura that lasts 3 seconds, setting a 0.5 second cooldown on her other basic abilities. The aura's duration is extended by 0.5 seconds for every allied champion who enters its radius, up to a maximum of 5 seconds.
After casting 3 basic abilities, Sona's next basic attack will deal
13 / 20 / 27 / 35 / 43 / 52 / 62 / 72 / 82 / 92 / 102 / 112 / 122 / 132 / 147 / 162 / 177 / 192 (6 + 7 / 8 / 9 / 10 / 15 at each level) (+ 20% AP) bonus magic damage, with an additional effect depending on the last basic ability cast.
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.
