Lillia

Lillia lives on momentum. Blooming Blows gives her stacking move speed each time one of her spells lands, and when she spins it hits everything around her, with extra true damage on the outer ring. The best Lillias keep circling the edge of a fight, nicking enemies with the tip of their swirl and speeding up after every connection. Her passive, Dream-Laden Bough, layers max-health damage over time onto any skill that hits a champion or monster, which explains how she shreds tanks even though she’s built like a mage.

Watch Out! Eep! pays off good spacing. It hits a wide area nearby, but the center takes heavy bonus damage, so anyone standing too close to her gets punished. Swirlseed works at range: she lobs a seed that slows whatever it hits, and if it whiffs, it keeps rolling until it runs into a wall or a target. It’s handy for chasing down runners or starting fights from awkward angles.

Sleep as a win condition

Lilting Lullaby is one of the rare sleep effects in the game. Each enemy holding Dream Dust becomes Drowsy, then drops asleep, and takes boosted damage if someone forces them awake. Cast it on several champions at once and her team gets a huge opening for follow-up, so Lillia often helps a teamfight as much as she deals damage herself.

She’s usually played top or mid as a Fighter-Mage hybrid and needs constant kiting with a 325-range kit and very little innate defense. A difficulty rating of 8 reflects how little room there is for positioning mistakes. Players who like a hit-and-run rhythm, slipping in and out instead of fully committing, tend to find her especially rewarding.
