Leona marks enemies with Sunlight for 3.5 seconds each time she damages them with an ability. At three stacks, basic attacks consume Sunlight on enemies, dealing bonus magic damage and the target takes 1-35% more damage from all sources for 1-4 seconds.
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 [S|L].
