Syndra is weak early but scales exceptionally well into the late game with her passive, delivering overwhelming burst damage.
Utilize her spheres for potent stuns (E) and zone control (W) to keep enemies at bay and secure favorable positioning.
Her ultimate is a powerful point-and-click execution and burst tool; time it correctly to secure crucial takedowns.
Do not use Scatter the Weak [E] before Fizz uses Playful/Trickster (E). Do not let him close in and use Dark Sphere to contest lane while farming lane.
