If you just sit back and wait for the late game, do not make any unnecessary plays, and perhaps roam when you have a good lane state with your jungler for a cheeky kill or 2, that will be ideal. That can only be done with good lane management and only if you manage to poke the enemy out for contesting anything with you.
Do not engage with any ranged champs beyond an E.
The champion is not hard to grasp, just hard to master.

They mainly run with First Strike for some early game action that is way more enjoyable than the Aery. But maybe some of you like to stay back and let the little critter do the job for you. It is up to the player. Both are good and fine.

I have tried all sorts of builds—Blackfire, Liandry's, and a different order of purchase—but so far this build is what has been treating me best (Ludens, boots, Lich Bane, Shadowflame, Rabadon (for the massive 1.3k dmg on Q2), and Void Staff). You have the massive Q2 damage from all the item procs, and the E is already broken as it is being used for poke in lane or just to whittle them down before a teamfight.

The laning phase is straightforward: kill the first 2 minions and farm LVL2 nonstop poke with E combined with last-hitting 2-3 minions with E.

Midgame skirmishes on bot lane (do not let the enemy team have a moment of chill and KS every kill the sooner you scale, the sooner the game will end).

Late game, wait for engage pop R and W and poke with E Q.
