Leona's spells charge any enemy unit damaged with Sunlight for 3.5 seconds. When allied champions deal any damage to those targets they consume the Sunlight debuff to deal 20 / 35 / 50 / 65 / 80 / 95 / 110 / 125 / 140 additional magic damage.
This additional damage is counted as the ally's damage and it will benefit from their magic penetration. Leona is unable to activate the additional damage herself.
Spell shields will block the application of the debuff, but will not block the detonation of a mark.
The damage dealt by Sunlight's mark is credited to the allied champion, not Leona. As such, the magic damage will benefit from their magic penetration and will apply any spell effects they have, including spell vamp.
Sunlight does not stack. Further applications of the debuff only refresh the timer.
Sunlight has a hidden passive which causes champions wearing sunglasses to take 1 less damage from Sunlight, such as Vayne. This extends to champion skins as well, even if their default skin does not normally wear sunglasses, such as Surfer Singed.
Shield of Daybreak
COST: 45 / 50 / 55 / 60 / 65 mana
COOLDOWN: 11 / 10 / 9 / 8 / 7
Active: Leona's next basic attack will be a shield slam, dealing additional magic damage and stunning the target for 1.25 seconds.
Shield of Daybreak will reset Leona's attack timer on cast. Additionally, it has a reduced delay between the next attack, allowing Leona three rapid autoattacks in succession.
Leona's basic attack range is increased by 30 (155 total range) while the effect is active.
Despite being an on-hit effect, Shield of Daybreak's damage will trigger spell effects as a single-target spell, including spell vamp, Rylai's slow and will cause Muramana's bonus damage to trigger twice with one autoattack.
COST: 60 mana
Active: Leona surrounds herself with a shield of sunlight, gaining bonus armor and magic resistance for 3 seconds. When the effect ends the shield bursts, dealing magic damage to enemies within 275 range of her. If Eclipse damages any enemies, the bonuses remain for an additional 3 seconds.
Champion clones such as Wukong'sDecoy will be damaged by Zenith Blade but will not trigger the dash.
Leona will automatically attempt to attack the target she dashes to.
COST: 100 mana
COOLDOWN: 90 / 75 / 60
Active: Leona calls down a beam of solar energy to a target location. After a 0.625 delay, it deals magic damage to all enemies within 250-range and slows them by 80% for 1.5 seconds. Enemies within 100-range are stunned for 1.5 seconds instead of being slowed.
