I know it's op, I just wanted to publish this Idea. Balance suggestions are accepted.

Lore:

Some say justice is blind. In Ionia, a fair judge was gifted with sight beyond anyone's dreams. However, she is not given the task of judgement. Ivera has accepted her duty of foreseeing wrongdoing and misguided punishment.
Born in a modest home to the far north, her parents dedicated their lives to the sea and what little the island provided. Being the yougest of 4, Ivera's life was of a child learning her parents life, so that she could make her own, until the day she envisioned a terrifying march spilling blood with each step. Her screams echoed though the village for days, until the elder decided to take her to Placidium, in search of help. No symptoms of disease and the innefectiveness of potions and medicine required more knowledge than the elder thought. For other several days, doubts arised, making everyone belive she was simply delusional with no return, until Soraka witnessed her terrified posture. She proposed Ivera could be gifted with the oracle's vision and asked to take and teach her.
After years of learning and acceptance, Ivera fully awakened to her powers foreseeing a young woman, seeking revenge, slaying the Convergence of Elders and spreading tyranny through Ionia.
She took upon her vision and made her persence felt to Syndra, who now waits eagerly to
to battle this young and insolent challenger.


Abilities:

P - The Oracle's Gift: Upon using an ability, Iveria gains true vision for 5 seconds. Also her health and mana regen are doubled if no allies are within a 800 unit radius.

Q - Oversight: Grants normal vision of a 500 radius area within 1000/1500/2000/2500/3000 unit radius. If a non-stealthed enemy is to be revealed, this grants true vision instead. The area will be marked for the duration.
  • CD: 55/50/45/40/35 seconds.
  • Sight duration: 2/3.25/4.5/5.75/7 (+0.25 per 50AP) seconds.
  • Cost: 60/70/80/90/100 Mana

W - Shift the Scales: Ivera deals 55/78/96/120/145 (+0.7AP) magic damage and steals 20% of the enemies' movemente speed, providing it to her and her allies within 500 unit radius, distributed equally, for 2.5 seconds.
  • CD: 18/17/16/15/14 seconds.
  • AoE Radius: 200.
  • Range: 1000
  • Cost: 50/65/80/95/110 Mana

E - Fairness: Passively provides 5/7/9/11/13 Magic Resist to another ally with the fewest maximum HP, within 800 radius. Iveria shields and ally for 60/85/110/135/160 (+0.7 AP) for 5 seconds. The ally, upon landing a basic attack on an enemy champion, steals 5/7/9/11/13 Armor for 1.5 second. Subsequent attacks only refresh this buff and only while the shield persists.
  • CD: 12 seconds.
  • Range: 850
  • Cost: 45/55/65/75/85 Mana.

R - Vision of Insight: Ivera extends her vision to 1500 unit radius, brushes included, and gains 15/35/55 movement speed for 7 seconds. If there are allies within 800 units, this also gives a shield of 100/125/150 (+0.25AP) to each ally in range, including Ivera, while her allies gain 10/20/30 movement speed for 2 seconds. This ability benefits from half CDR, maxing at 20%.
  • CD: 35 seconds.
  • Cost: 125 Mana.


Playablility:

There ought to be two rings visible to Ivera's player, marking 800 and 500 units. She is thought out to be a supportive scout, provided with her vision and mobility.
Vision is very valuable so I had to design some obvious downsides (I think), comparing to other supports, while making her solo laning rather bad:
  • lack of hard cc.
  • expensive abilities with long cd's.
  • tone down her ratios.
  • a "useless" ability (Q).
However, she still has a very supportive trait, included in shields and passive resistance buff.
Shift the Scales steals 20% to each enemy. The bonus given to the allies will be the number of enemies hit divided by the number of allies in range, times 20%. Eg1: ability hits 2, 4 allies in range, each ally gains 10% bonus. Eg2: hits 4, only Ivera in range, get 80%.
I have a problem with Fairness, since it can't be simply better than Consecration.
