Passive - Apparently it works like Lux's passive, but only allies can activate it
Q - Shield of Daybreak: Leona's next autoattack deals an addtional 40 magic damage and stuns the target for 1.25 seconds
W - EclipseL Leona raises her shield to gain 30 bonus armor and Magic Resistance for 3 seconds. When the effect ends, she deals 60 magic damage to nearby enemies and prolongs the effect for a bonus 3 seconds if any enemies are struck.
E - Zenith Blade: Leona projects a solar image of her sword, which deals 60 magic damage to all enemies in a line. When the image fades, the last enemy champion struck will be briefly immobilized and Leona will dash to them.
R - Don't know the tooltip. AoE that slows and I think stuns in the center.
