When Myra damages an enemy champion, she deals bonus true damage equal to 4 / 6 / 8 / 10% of enemy's max. health, and gains a shield equal to 70% of this amount for 3.5 seconds. This cannot happen on the same enemy for more than once every 35 seconds, but auto-attacking the enemy reduces this period by 0.5 seconds and damaging them with a spell reduces it by 1 second instead.
If the spell deals damage to multiple units, the true damage is reduced to 1 / 1.5 / 2 / 2.5% of enemy's max. health, but the shield value is increased to 100% of the enemy with the highest max. health at the time the ability dealt the bonus true damage.
COST: 30 / 65 / 100 / 135 / 170 health
When Myra damages an enemy champion, she gains the ability to use Boomerang Effect for 4 seconds, a single-target collision skillshot, which deals magic damage equal to 30 / 65 / 100 / 135 / 170(+ 50% AP) + 1 / 3 / 5% of enemy's missing health, but takes a portion of Myra's health, and the shield from Backfire if she has it (20 second cooldown).
COST: 70 / 80 / 90 / 100 / 110 mana
Active: Myra fires a beam at a target 325-units location, which will deal magic damage after an 0.725 second delay and slow all enemies hit by 30% for 1.5 seconds.
Wave of Energy has no cast time and will not interrupt Myra's previous orders.
RANGE: 1500 (2000 if Flare of Devastation hits a champion)
COST: 80 / 90 / 100 / 110 / 120 mana
COOLDOWN: 22 / 20 / 18 / 16 / 14
Active: Myra corrupts a 350 units area with powerful magic, which after 1.25 seconds deals magic damage to all enemies still standing in it. Enemies standing in the center 125 units area are stunned for 0.5 seconds and take an additional 30% magic damage.
Passive: Killing an enemy champion with Boomerang Effect grants Myra 35 ability power permanently.
Magic Damage: 200 / 275 / 350 (+ 55% AP)
Active: After channeling for 1 second, Myra fires a very long range beam which deals magic damage to the first enemy champion in its path, and stuns them for 2 seconds.
While the enemy is stunned, Myra gains 20-150% movement speed when walking towards the target (based on how far away they are: less than 2000 range for 20%; 150% for 4750 range or more; increases by 1% for every 21.15 distance), Corrupted Magic's range is increased by 500, and its delay time is reduced by 0.75 for 2 seconds. If she manages to deal damage to the target while it is still stunned, it will take an additional 20% damage from all of her spells for 4 seconds.
Flare of Devastation is a single target channeled skillshot, which will grant bonus ability range and movement speed if it hits an enemy champion, and will de-buff the champion hit if they take damage while stunned from this ability.
