Sona rework "Auras, Arpeggios, and Fermatas"

Passive: Musicality Arpeggio When Sona casts a spell, she gains an aura (900 range) based on the spell she cast. Auras will fade after 5 seconds if Sona casts another spell. Casting the same spell again will not cause the Aura to fade, simply adding its own effects to the mix. Sona can have 3 auras active at once. If Sona is stunned, silenced, suppressed (etc) she will cease her auras. Fermata If Sona has three auras, she will enter a fermata and maintain her current auras for up to 8 seconds. Casting basic spells during a fermata will not change your auras, but it will reduce the remaining duration Power Chord If Sona does a basic attack during the fermata, it will be empowered. The effects are based on what auras she had and how much of the fermata duration was left (The smaller the remaining duration, the greater the effect)

Q: Hymm of Valor 7/6.5/6/5.5/5 second CD 50 mana

Sona sends out a rapidly expanding wave of sound, dealing 50/55/60/65/70 (+.3 AP) magic damage in a line. Sound echoes out from champions hit, dealing 20/25/30/35/40 (+.15 AP) magic damage in a small area for each instance of Hymm. (This projectile gives vision of the area it passes over). Aura: For each instance of Hymm, allies in the aura deal an additional 2% (+1% per 100 AP) of their damage output as true damage. Power Chord: Sona stuns her target (with Awe) for 0.1 seconds and deals 5-75/10-80/15-85/20-90/25-95 (+.15 AP) magic damage for each instance of Hymm.

W: Aria of Perserverance 7/6.5/6/5.5/5 second CD 70 mana

Sona applies a 5/10/15/20/25% (+2% per 100 AP) damage reduction to all allies within 900 units, lasting 1.5 seconds.

Aura: Sona grants 5/10/15/20/25 (+.05 AP) HP5 and half that in MP5 to all allies in the aura for each instance of Aria.

Power Chord: Sona calms her target, reducing their damage output by 1-3/5-7/9-11/13-15% (+1% per 100 AP) for each instance of Aria.

E: Song of Celerity 7/6.5/6/5.5/5 second CD 40 mana

Sona grants herself and nearby allies an 80% (+3% per 100 AP) movement speed boost, decaying to 20/25/30/35/40% (+3% per 100 AP) over 3 seconds.

During this effect, Sona and her nearby allies ignore unit collision and have 50% slow resistance.

Aura: Sona grants 10/15/20/25/30 (+.05 AP) movement speed to nearby allies for each instance of Song.

Power Chord: Sona slows her target by 5/10/15/20/25% (+2% per 100 AP) for each instance of Song.

R: Crescendo 130/120/110 second CD 100 mana

Sona sends out a wave of sound in a line, dealing 150/250/350 (+50% AP) magic damage and stunning units hit for 1.5 seconds, forcing them to dance.

Additionally, Sona doubles the effects of all active auras, extending her fermata by 4 seconds if she is in one. This extension will not reduce the effectiveness of Power Chord; you will be allowed to sit on a max power chord for 4 seconds.

tl;dr

Auras are back. Sona can stack them, up to 3. She can mix them or go all out into one. If you have 3 auras, your next auto is a power chord. Effects based on aura type. Power based on skill levels and how long you waited. Q is a line skillshot. Q aura is something like Amumu passive. Staccato now applies a ministun. W is now % damage reduction. W aura gives high amounts of regen. E is a lot of instant mobility. R now damages minions and monsters. Casting crescendo amplifies your auras and extends them. R passive removed.
