When Myra is damaged with a spell, she returns 15 / 17.5 / 20 / 22.5 / 25% of that damage as magic damage to the caster (True damage is excluded). This cannot happen on the same target more than once every few seconds.
Myra generates one Charged Bomb periodically, used in the Active part of this ability.
Active: Places a Charged Bomb at a target 250 units location which arms after 1 second. The charged bomb lasts 90 seconds and explodes upon contact with one of Myra's spells or upon contact with an enemy that is within 125 units, dealing magic damage to all enemies within 175 units and revealing them for 3 seconds. There can be a maximum of 4 bombs at most at any time on the map, and placing a Charged Bomb that will surpass this limit will remove the earliest placed Charged Bomb on the map.
Active: Corrupts a 300 units location with magic, which deals magic damage initially, and after 0.75 seconds of cast. Enemies that have been damaged with Power Steal in the last 3 seconds are slowed by 40% for 1.5 seconds by the second portion of this ability.
Passive: Damaging an enemy champion with a spell stores 20% of the damage dealt as Magical Force, which can be used by the Active part of this ability. The stored damage caps at 180 - 540 (based on level), based on level.
Active: Myra consumes 25% of her current stored Magical Force and channels it through her next spell, dealing additional magic damage equal to a percentage of the consumed Magical Force. If Myra is at full Magical Force and consumes some of it, the channeled Magical Force will deal true damage instead.
Bonus Damage: 100 / 115 / 130% of consumed Magical Force
If some Magical Force is consumed while there is already some to be channeled, it will replace it, but not return it back to the storage.
