Innate:Kayle ascends through four forms before reaching her divine state, each granting her additional bonuses. She ascends upon spending a skill point at levels 1, 6, 11, and 16.
Level 1 - Zealous:Kayle'sbasic attacks grant her 6%(+ 1% per 100 AP)bonus attack speed for 5 seconds, stacking up to 5 times for a maximum of 30%(+ 5% per 100 AP). She also becomes Exalted while at maximum stacks, gaining 8% bonus movement speed.
Level 6 - Arisen:Kayle becomes ranged and gains 350 bonus attack range for a total of 525.
Level 11 - Aflame: While Kayle is Exalted, her basic attacks also launch a wave of fire forward that deals 15 − 35 (based on Starfire Spellblade's Rank)(+ 10% bonus AD)(+ 25% AP)magic damage to all enemies it passes through (affected by critical strike modifiers).
Level 16 - Transcendent:Kayle gains an additional 100 bonus attack range for a total of 625 and the bonuses from Zealous are permanent now, no longer required to be stacked up.
The stacking attack speed is tracked via a buff called Zeal, while the maximum stacks bonus grants the buff Exalted.
Subsequent applications will also refresh the duration of all stacks, but all of them are lost when expired.
If Kayle is in her attack animation after the stacks expire, she gains another 0.5 seconds to refresh/stack Zeal.
Each stack grants attack speed based on the amount of ability powerKayle has at the time the stack is acquired and will not update when ability power is changed.
For example, if a stack is acquired while Kayle has 100 ability power, it will grant 7% attack speed. If an additional 100 ability power is gained immediately afterwards (for a total of 200), the next stack will grant 8%. If all ability power is then immediately lost, the next stack will only grant 6%.
Arisen
Basic attacks within 175 will still use Kayle's melee basic attack animations and do not utilize projectiles.
Due to this fact, projectile blocking effects cannot intercept basic attacks while Kayle's target is within her "melee" range.
Aflame
Basic attacks against structures do not trigger fire waves.
While at 4 stacks of Zeal, the next on-attack reaching the fifth stack will be empowered by Aflame, releasing the first fire wave.
Transcendent
Zeal and Exalted buffs swapped to a new buff that grants the benefit of both and it is not visible on Kayle's HUD.
This buff also updates its attack speed value whenever a stat update happens and ability power is changed, however, it does not track ability power from other buffs, unless they have been specifically special cased. The following buffs are not special cased yet and will not grant bonus attack speed:
A wave consists of three projectiles for the hitbox and a fourth for visuals.
The hitbox projectiles spawn 75 units behind Kayle, travel through her, and are destroyed once they've traveled 850 units. Their technical details are:
Because Kayle is both a melee and ranged champion, she can purchase both ranged and melee exclusive items at anytime, but their effects will function depending on her current range type; the same principle also applies to runes.
However, keep in mind that, prior to ascending to Arisen, Starfire Spellblade also changes this behaviour based on its usage.
Waves are fired in the direction that Kayle is facing. Changing that during the early animation via Flash will also change the direction of the wave.
Each ascension has an unique animation and a voice line. (See: Kayle's quotes)
The ascensions' animation will override the current one, but it does not cancel Kayle's current action, nor her previous orders.
Active:Kayle conjures a portal in front of her that faces the target direction. After a 0.25 second cast delay, a celestial sword launches forward from it.
The sword expands upon colliding with an enemy. Targets struck are dealt magic damage, slowed for 2 seconds, and have their armor and magic resistance reduced by 15% for 4 seconds.
The portal is created at the start of the cast time and it does not follow Kayle's movement, using Flash or getting displaced won't change its position nor direction.
The explosion consist of 5 hitboxes, forming a cross-like shape centered 100 units ahead from the impact in its direction. Their technical data can be seen below and visualized on the image to the right.
The left side shows projectile's width and the total area traveled if it does not hit a target, while the right side shows the explosions when it hits a target.
ExplosionCenter: 100 radius
ExplosionLeft: 150 distance, 125 width
ExplosionRight: 150 distance, 125 width
ExplosionBackward: 100 distance, 90 width
ExplosionForward: 400 distance, 90 width
The resistance reduction is applied after the damage has been dealt.
Interactions & Other
The visual effects of the explosion shows the blade and guard of Kayle's swords.
The cast delay represents how much time needed for the projectile to spawn.
Since patch V9.17, the cast time matches the cast delay. The ability before had a 0.5 second cast delay and the cast time matched Kayle's basic attack timer.
The resistance reduction can be tracked on the HUD as a debuff called Sundered.
Active:Kayle and the target allied champion are healed and gain bonus movement speed for 2 seconds.
Heal:
60 / 90 / 120 / 150 / 180 (+ 30% AP)
Bonus Movement Speed:
24 / 28 / 32 / 36 / 40% (+ 8% per 100 AP)
If cast without a valid target, or self-cast, Celestial Blessing will automatically target the closest allied champion in range, prioritizing the one with the least amount of health.
Passive:Kayle deals bonus magic damageon-hit. The fire waves' from Divine Ascent have equal base damage to this effect's base damage.
Passive Damage:
15 / 20 / 25 / 30 / 35 (+ 10% bonus AD)(+ 20% AP)
Active:Kayle kindles her blade, empowering her next basic attack within 6 seconds to have an uncancelable windup and deal additional bonus magic damageon-hit that is capped at 400 against monsters. This effect also causes the attack to be ranged with 525 range, even before ascending to Arisen.
Bonus Magic Damage:
8 / 9 / 10 / 11 / 12% (+ 2% per 100 AP) of target's missing health
After ascending to Aflame, Starfire Spellblade is upgraded, causing the basic attack to explode centered on the target, dealing its damage to all enemies within and applying on-hit effects to them. This effect is a standard basic attack just in an area of effect and still affected by critical strike modifiers.
𝐏𝐄𝐍𝐃𝐈𝐍𝐆 𝐅𝐎𝐑 𝐓𝐄𝐒𝐓: All parry interactions are marked for retesting because of patch V11.1 changes.
Interactions & Other
While the active's effect is up, a circle is visible to Kayle, indicating her range, however, this circle only takes into account Divine Ascent's effect on her range, not other sources such as Rapid Firecannon.
The increased range (with the item's effect included) will be 675 prior to ascending to Transcendent, after which it's 725.
To clarify the description, Starfire Spellblade can behave both as a ranged and melee attack based on how far the target is prior to Kayle ascending to Arisen, after which the attack will be always using ranged standards.
If the target is 200 units away or closer, the attack will be considered melee. This also uses her melee animations, not utilizing projectiles even after ascending.
If the target is over 200 units, the attack will be considered ranged.
To further expand on this: Using the ranged empowered attack will change Kayle's range type to ranged while the projectile is alive. This means that if the target could outrun the projectile, Kayle would be stuck on being ranged, although the bonuses from the active are not kept. While it's unlikely to be on this temporary ranged state for longer than half a seconds during a normal playthrough, it is possible to achieve few seconds when specific conditions are met.
Keep in mind that while on-hit effects will be applied to all targets in the explision, on-attack effects are only applied once per basic attack, not per target hit.
Single-use on-hits, such as Spellblade, will be applied to the main target.
If the main target died prior to the projectile reaching them, or if it was a jungle plant, the effects will be applied to the closest target from the explosion's center.
Despite being one cast instance, Starfire Spellblade triggers Muramana'sShock twice on each target, dealing normal bonus damage after the basic attack and increased bonus damage after the spell, totalling at ( 5% / 4.2%)maximum mana(+ 6% AD)bonus physical damage.
Active:Kayle grants herself or the target allied champion invulnerability for a few seconds once the cast time begins, conjuring swords of holy fire, and highlighting a fixed area around the target.
Duration:
2 / 2.5 / 3
Upon completing the cast time, the swords rain down, dealing magic damage to enemies in the highlighted area.
Magic Damage:
200 / 350 / 500 (+ 100% bonus AD)(+ 80% AP)
Divine Judgment will prioritize casting on allies over Kayle.
Divine Judgment's cast time does not interrupt movement.
The cast time will finish even after Kayle's death.
Because internalraw damage ignores invulnerability, the target may still die via Nexus Obelisk, but the ability will finish at their corpse's position regardless.
Prior to becoming Transcended, casting Divine Judgment refreshes the duration of Zealous stacks.
If casted on herself, Kayle's basic attack range is reduced to 400 during Divine Judgment's cast time to bring her within the effective range of the ability if attack commands are issued on an enemy.
The area around the target does not appear if the target is not visible to the enemies' point of view.
While the target is invulnerable, a number indicator will appear beneath them whenever they would receive damage to show the amount that was entirely mitigated. This is calculated pre-mitigation, or before resistances and reductions are taken into account.
Interactions & Other
Rapid Firecannon'sEnergized behaves strangely with the set basic attack range, causing it to go from 400 to 385 over 4 stat updates. (So 400 - 390 - 387 - 385)
Upon completing the cast time, the proper range needs 2 updates to set in. ( 660 - 675 while Arisen; 710 - 725 while Ascended)
Gaining Energized during the cast time will cause the range to cycle between 525 and 550 until the cast time finishes and set to the proper range after 1 update.
Selling Rapid Firecannon during the cast time sets the range to be 250
The invulnerability can be tracked on the HUD as a buff called Intervention.

Notes
As mentioned in some of the ability descriptions, Kayle's basic attacks within 175 units will always use her melee animation, even after becoming ranged, not utilizing projectiles.
Basic attack empowered by Starfire Spellblade have a 200 "melee" range.
Upon becoming Aflame, Kayle's portrait icon for certain skins will change:
On the Original skin becomes .
On the Silver skin becomes .
On the Viridian skin becomes .
On the Battleborn skin becomes .
On the Aether Wing skin becomes .
On the Riot skin becomes .
On the Pentakill skin becomes .
On the PsyOps skin becomes .
Keep in mind that from others' point of view, only the Original skin is shown.
Trivia
The projectile speed of Kayle's basic attacks are the second highest in the game with its 5000 speed among all ranged basic attacks that utilizes projectiles. Aphelios'Severum gun has the fastest at 92400 speed, while Soraka has the slowest at 1000 speed. The average is between 1500 and 2000.
The first buff from Kayle's innate passive (Zeal) shares its name with the item Zeal.
In Ultimate Spellbook, Kayle ascends without the player's input. This is caused by the fact that the choosen Ult-ernate Summoner Spells are automatically ranked up when the required levels are reached, which also matches the levels that the player may initiate the ascensions on.
While patch the patch notes specifically mentions Tear of the Goddess, the actual change made Starfire Spellblade be a single cast instance, rather than two indicidual ones (basic attack and spell).
Now only gives one stack for effects such as Electrocute or Phase Rush, instead of two.
