(Innate): Kayle's autoattacks against enemy champions reduce their armor and magic resistance by 3% for 5 seconds. This debuff stacks up to 5 times.
Holy Fervor is a passive ability that provides Kayle with an on-hit effect, reducing the attacked champion's armor and magic resistance by a percentage, lasting for 5 seconds. Subsequent autoattacks stack the debuff up to 5 times, refreshing the duration and increasing the defense reduction effect.
Attacks made while Righteous Fury is active will apply the debuff to Kayle's main target.
The armor and magic resistance reduction will not apply to any secondary targets hit by Righteous Fury's splash damage.
The debuff stacks additively with itself. At five stacks the enemy will have its armor and magic resistance reduced by 15%.
Reckoning will damage Black Shield and the slow will be negated.
Damaging an enemy with Reckoning applies one stack of Holy Fervor on the target.
If Kayle launches the missile at an opposing Fizz and if he uses Playful before the missile hits, the missile won't do any damage or apply the slowing effect.
Reckoning can apply one stack of Holy Fervor on a minion/monster. With maximum cooldown reduction and standing extremely close to the target with good latency, up to 5 stacks can be achieved on the minion/monster. This is the only instance known where Holy Fervor can be applied to minions/monsters. It is unknown if this is intended or not.
(Active): Blesses a target allied champion, healing them and increasing their movement speed for 3 seconds.
Divine Blessing is a targeted ability that heals a target allied champion and increases their movement speed for a short duration.
Divine Blessing has no cast time, but Kayle can't attack or use abilities (can move) during the animation (0.15 seconds)
(Active): Kayle harnesses her righteous fury to increase her attack range by 400 (to 525) for 10 seconds. These attacks splash, dealing magic damage based on her attack damage and ability power to nearby units, and additional magic damage to her primary target. This splash damage does not affect turrets.
Righteous Fury is a point-blank self-targeted ability that grants Kayle's autoattacks extra range and bonus damage, and causes them to deal splash damage in a radius around the main target. On each attack Kayle deals bonus magic damage to the attacked target and all enemies within the splash radius take a base damage plus a percentage of her attack damage and ability power.
Righteous Fury procs spell vamp and Rylai's slow similarly with all area of effect spells and abilities with diminished effect.
Kayle's autoattacks are considered ranged for the duration.
Despite functioning like a on-hit effect it behaves nothing like it, as it procs spell vamp, Rylai's slow, and Liandry's Torment, and ignores blinds and dodges (only the magic damage portion hits. The main damage of the autoattack still misses on these cases).
