Sona's basic abilities use the stance mechanic. In addition to their activation effects, her basic abilities each grant a unique and persistent aura until she activates a different basic ability to change stance. The previous aura persists for 1 more second after Sona enters a different stance. Changing stances sets off a 0.5 second cooldown on Sona's basic abilities.
