[Champion Rework]: Sona: Maven of the Strings
#Passive: Power Chord
When Sona casts an ability, she generates a temporary 375 radius aura for four seconds and generates a stack of Power Chord. Each stack of Power Chord improves the utility of Sona's auras, and stacks up to two times (+1 per level of Symphony of Justice). Once Sona reaches two stacks, she can expend these stacks of Power Chord by attacking an enemy or structure, dealing bonus effects depending on her song, and deals 13 / 20 / 27 / 35 / 43 / 52 / 62 / 72 / 82 / 92 / 102 / 112 / 122 / 132 / 147 / 162 / 177 / 192 (+20% AP) bonus magic damage instead. Deals 10% increased damage for each stack of power chord after the first. All stacks will fall off after four seconds.
There is a 0.3 second delay between casting other spells after a spell cast.
#***Q: Hymn of Valor *** Range: 850 Mana Cost: 40 / 50 / 60 / 70 / 80 Cooldown: 10
Active: Sona sends out a single skillshot sound wave that deals 20 / 40 / 60 / 80 / 100 (+50% AP) plus 8% of the target's current health as magic damage. If it hits an enemy champion (ignores minions), it will bounce back to the same location Sona cast it. If Sona intercepts it, the cooldown is instantly reset, half of the mana cost is refunded, and the target is revealed for 2 seconds, with the initial half of the duration being true sight.
Aura: Sona and tagged allies deal 4 / 8 / 12 / 16 / 20 (+2 per PC) bonus magic damage on auto attacks for the next 1.5 seconds (+0.5 seconds per PC).
Power Chord - Staccato: Sona reduces the armor and magic resistance of her target by 5% (+3% per 1 PC) for two seconds.
#W: Aura of Perseverance Range: 1000 Mana Cost: 50 / 60 / 70 / 80 / 90 Cooldown: 10
Active: Sona shields herself and the most wounded allied champion by 65 / 95 / 105 / 135 / 165 (+ 20% AP) for up to 2.5 seconds. The duration is increased by 0.5 seconds for each ally she tags with the aura.
Aura: Sona heals herself and her allies in her aura's radius for 5% of their maximum health over eight seconds for three seconds. (Heal per second increased to over 7 / 6 / 5 / 4 / 3 seconds per stack of PC.)
Power Chord - Diminuendo: Sona reduces the target's damage output by 20% (+ 4% per 1 PC) for two seconds.
#E: Song of Celerity Radius: 375 Mana Cost: 60 / 65 / 70 / 75 / 80 Cooldown: 15
Active: Sona gains 22 / 24 / 26 / 28 / 30% bonus movement speed that decays down to Song of Celerity's aura bonus over one second. The decay rate is decreased by 0.5 seconds for each ally she tags with the aura.
Aura: Tagged allied champions gain 10 / 11.5 / 13 / 14.5 / 16% bonus movement speed for 1.5 seconds (+0.5 seconds per PC).
** Power Chord - Tempo: Sona slows the target's movement speed by 25% (+5% per 1 PC) for two seconds. **
#R: Symphony of Justice Range: 850 Radius: 500 Mana Cost: None Cooldown: 150 / 125 / 100
Passive: Sona's maximum Power Chord stacks are increased by 1 / 2 / 3.
Active: Sona must have an aura active, and at least two stacks of Power Chord before casting this ability. Sona then creates a golden aura that increases the attack speed of all allies in the radius by 20% that increases gradually to 60% over 3 / 2 / 1 seconds for four seconds as well as providing the effects of the aura that was selected for an additional 4 seconds. Her Power Chord becomes Crescendo for the duration.
Power Chord - Crescendo: Sona's next auto attack gains 300 range and becomes a linear area of effect that stuns and forces all champions to dance within 350 width for 0.5 seconds (+0.2 per PC)(+0.1 per enemy champion hit) and deals 100 / 200 / 300 (+100% AP) bonus magic damage to all enemies caught within the blast (only the target will take the passive power chord damage, subsequent targets will take only the bonus damage.)
