Lillia vs Warwick

Hit with the edge of Blooming Blows (Q), not the center: only the outer edge adds true damage.

Hit enemies with your spells and keep your distance: Blooming Blows (Q) gives you a stack of move speed on each hit, enough to kite and dodge.

Start the fight from range with Swirlseed (E): it damages, slows and reveals, and if it hits nothing, it rolls on to the first enemy or wall.

Before Lilting Lullaby (R), hit as many enemies as you can: Dream-Laden Bough (passive) marks every target of your spells, and only marked ones fall asleep.

Keep your health above 50%: below that, Blood Hunt (W) gives him speed toward you and attack speed, three times more below 25%.

When he drops below 50% health, finish him fast, with CC if you have any: Eternal Hunger (passive) then heals him with each auto, three times more below 25%.

If you have a dash, don't count on it to escape his held bite: Jaws of the Beast (Q) makes him follow all your movement, then leap behind you.

In teamfights, stay behind your tankiest allies: Infinite Duress (R) suppresses the first champion hit, and its range grows with his move speed.

If you have Grievous Wounds, apply it to him: his autos heal him at low health, and Infinite Duress (R) heals him for all the damage it deals.
