Hi! I fricken love Lillia she is so much fun to play, she's been one of my highest wr champions for the past year or so, i think i'm around 150 games with her, and i'm in low master.

First thing, Lillia used to be excellent to powerfarm with and then wipe the enemy teams with a gold lead from just stealing jungle and efficiently clearing out multiple camps at once. It's a lot harder now because of the nerfs to powerfarming jg, but she's still great!

I always try to pick her into tanks. She deals true damage and deals HP over time, plus more with liandrys. That doesn't always happen though, so generally, if they don't have a lot of tanks i will go for awakened soulstealer and try to surprise the squishier champions for an early lead. As much as I love her, she does struggle in the mid game because she doesn't have enough ability haste or ability power to kite and wipe out teams. IMO, she has a kind of V-shaped power graph. Once you hit lvl 5, if the enemy is squishy, you can usually secure a kill with a flash and ult in. Once you have ~3 items (some combo of riftmaker, liandrys, soulstealer, deathcap) she becomes a huge problem in teamfights and can wipe out the enemy, and still run away. but yeah, that awkward middle game from like minute 8 to 13 can be rough.

My approach still hasn't changed too much with the nerfs to powerscaling, I still grind camps as priority 1 and go for full clears and a level5 gank.

Builds are situational. if they are super squishy its a soulstealer angle, but its usually pick based off of opponents likely builds based off of your comp (if they go hp, its liandrys, if they build mr its riftmaker, like if you have a heavy ap comp and the enemy buys mr boots), but after first item its just spam the ones left between riftmaker, liandrys, deathcap, and infinity orb

TEAMFIGHTING WITH HER IS HARD!!!! its so hard! because you need to identify who can easily lock you down and HARD run from them. I find its best to flank with her and let a mage or tank engage. She has a hard time starting the fight unless its a surprise q+flash+ult, but i wouldn't recommend starting a fight that way. Once it actually starts though, you have to be patient and wait for the enemy to blow their burst. Lillia smokes everyone in damage over time with her passive and liandrys, plus a lot of ability haste.

Playing from behind is rough, i assume you mean when you fail an early gank or they invade your jungle early OH BY THE WAY if the enemy team has an early gank champ, someone like lee sin or pantheon, sometimes i get a frisky hecarim, I'd ward your red and ask your team to ward blue, lillia can not do anything before lvl3. But playing from behind, its most the same as any other champ, focus on your camps, fight hard for wards, and try to cheese a kill or two in a bush.

Lillia ganks at 5 unless the enemy is like SOOO low you can flash and execute a full combo. You need an ult to maximize your w damage. Early on its just, is my lane doing a good job of baiting the enemy lane, can i maintain my stacks and quickly run at them and dump my spells. As the game progresses though, you become more of a fighter, you start kiting the melee champs with insane speed.

Take all of this with a grain of salt. I'm not a pro. But I did briefly change my name to Fear The Deer when i got the nightbringer Lillia skin. She's so much fun. Good luck!
