Lucian is a very strong lane bully. Try to hit level 2 first, and instantly take control by using your e towards the other adc, using your passive on them, then followed by q passive, and back off. You will chunk them hard and at lower elo they will most likely be too scared to react. Dont spam your spells, or you will run out of mana fast. Try to look for opportunities to line up your Q on a minion to hit an enemy chanpion as well, as it has a much higher range than its cast range. Your W is pretty useless and is just a huge mana drain. Only use your W to proc your passive again in all-ins, or, on the rare occasion when an enemy gets away with 25 health, finish them off with it as it has a very long range.

You are pretty damn strong in mid game. Keep farming and stay with your team. Lucian is a pretty good split pusher, pressure lanes and when you are fighting, remember to proc your passive as much as possible. A funny little tip that only works in lower elo is : If an enemy is on an objective, whether it be your mid tower or dragon, use your ult to "scare" them off. This might sound crazy, but ignorant players who overestimate The Culling get intimidated by it and you can use it as a disengage. In reality, unless you eat every bullet from The Culling, or the Lucian is extremely fed, you wont get hurt that badly, unless you have no armor whatsoever. Trust me, it actually works.
