After using an ability, Kagiya Surges and gains 15 -> 51% + 50% bonus +5% per 100 AP attack speed for 4 seconds, doubling her Critical Strike Chance for the duration. Her first attack after using an ability will always Critically Strike.

Surges can stack indefinitely, but each will last only 4 seconds.

Kagiya's Critical Strikes use two projectiles, but each projectile only deals 60% damage. Each projectile has a chance to Critically Strike separate from the main attack. Each applies on-hits at 60% strength.

Additionally, Kagiya's Critical Strikes are modified, dealing 3% + 1% per 50 AP + 10% Critical Strike Chance (Max: 10%) as %max health magic damage, and will heal her for 10 -> 25% + 10% per 100 AP of the pre-mitigated damage dealt on-attack, per projectile.

Kagiya's basic attacks will have additional properties while she Surges.

When Kagiya lands the killing blow on an enemy Champion, she will gain a free Surge at random.

Kagiya sends a shockwave forward on her next basic attack, propelling herself backwards if she hits a valid target, and over terrain. She deals 30/50/70/90/110 + 125% bAD +50% AP damage to the first target hit, then half that damage to all enemies within a 300 unit cone behind the initial target. If the first target dies, the ability refreshes its cooldown and Kagiya’s next basic attack is guaranteed to critically strike.

For the next four seconds, Kagiya’s critical strikes will instead deal 5 -> 14% + 5% per 100 AP missing health physical damage on-hit. This passive can stack as long as Kagiya is recasting Thunderwave. If her basic attack kills the initial target, it will bounce to the nearest target, prioritizing enemies that would be killed by it, but reducing 5% less damage per leap. If she critically strikes, it will always chain to at least 2/3/4/5/6 additional targets, if enough targets are in range.

During Thundersurge, Kagiya’s basic attacks are not projectiles (she shoots bolts of lightning).

Kagiya pulls ice from the sky, pelting an area with hailstones for 4 seconds and slowing all enemies by 15 -> 51 (+50% bonus attack speed) for the duration.

For the next four seconds, Kagiya’s basic attacks will apply half of Call of Hail’s slow on-hit, stacking with Call of Hail. Slowed targets take 20 + 50% Critical Strike Chance more damage from Kagiya.

During Hailsurge, Kagiya’s basic attacks come from above (she is calling down stones of hail).

Kagiya blasts air in all directions around her and knocks back all enemy targets hit, dealing 130/160/190/220/250 + 90% AP magic damage, and granting Kagiya a 20/40/60/80/100 + (50% bAD + 60% AP) shield for each enemy Champion hit by the ability.

Until the Four Winds shield breaks, Kagiya will be ghosted and gain 10 -> 46 (+50% critical chance) movement speed.

Kagiya summons a circular storm over herself with a radius of 600/800/1000 units, dealing damage to all enemies.. While within it, Kagiya is ghosted and can basic attack all enemies being damaged by it, regardless of their distance to Kagiya. Kagiya must have an active Surge to cast Rolling Thunder. Casting Rolling Thunder will extend that Surge by 10 seconds, while within the storm. Leaving the storm will end the Surge and Rolling Thunder.

The storm stuns all targets hit for 1.5/2/2.5 seconds, and Kagiya will dash to the edge of her basic attack range to any target she basic attacks within the storm.

The storm will apply Call of Hail's slow, and Kagiya deals Hailsurge's bonus damage to all targets within the storm. Kagiya's basic attack range increases by 200/250/300.

The storm knocks all enemies towards the center of the storm and will drag all enemies towards the center for the first 3 seconds.

Kagiya’s Four Winds Shield is refreshed when the ability is cast and again after 5 seconds have passed.
Any enemies who remain in the storm when it ends will be violently expelled towards their Nexus by 700/900/1200 units.
