So you came here to learn the hardest champion in the Bot lane, well the hard part is actually his passive but comes with practice. the other reason you picked up this champ is that he is on free champion rotation and you needed a quick guide to teaching you how then you've came to the right place!

okay here is the English part of this guide:

any time he casts a spell [like Q, W, E] he shoots two attacks instead of one the next time you target an enemy, they do track if you were in range when you fired it so its guaranteed damage. that's it to the entire champion, pretty simple, huh?

well, Lucian has more tricks up his sleeve as you get used to his passive.

Basic combos:

Q then auto-attack
W then auto-attack
E than auto-attack

Here comes the nitty-gritty of this entire guide. The explanation of the Runes setup!

so if you are going the standard route stop here, otherwise continue:

okay, it's Precision Primary and Inspiration Secondary, this will give you a boost in AD, free boots, and mana. The Precision Tree is basically the bread and butter for most ADC champs. This includes Lucian. Since his entire kit revolves around his passive so should his rune setup. In the Precision tree, take Press the Attack for the keystone, this will maximize Lucian's damage in lane. The easiest way to proc the keystone is by doing [Q + auto-attack]. Next, take triumph, this will allow for sustain in the lane when you takedown an enemy. After that, take Legend: Alacrity to boost your attack speed. Finally, take Coup de Grace to help with finishing your enemies when they are low.
Ok since Inspiration is secondary, we get the free boots and free mana from Biscuit Delivery and Magical Footwear.


Now if you are using the tank Runes here is the reason for taking them. one you have a shield from overheal plus you have sustain when your grasp of the undying procs and overgrowth. by grabbing a tanking item while having this rune setup will make you unkillable. honestly, if you want more reasoning on why you should take tank runes, well I played a game with them on Caitlyn and she was able to stay in the lane only needing to go back a couple of times. but this setup is highly experimental and most people would think that you are trolling anyways.

the easiest way to farm on any ADC or champ, go to the Practice Tool and get in-game with the character you are going to play for that session and just try to grab every minion without an enemy till you hit level 10. by then in any normal game you would have to group up with your team to grab an objective. you want results instead of hoping to get better overnight, I'm sorry that does not exist here in this dimension, however, with this, I was able to out CS any match up, even the bad ones. yes, I was able to out cs my perfect counter, of course, I died a lot but I was still getting more items then they were and I was able to win every game that I had gave my self the lead.
The reason I win my bad matchups is that 15 cs is equal to one kill. Farming is your lifeline as an ADC, you are not to kill the enemy all the time but is to get really powerful, really, really quickly. Of course, kills are the whipping on the ice cream sundae

Legend
AA = Auto-Attack

honestly, you will create some combos on your own but here some more
some advanced combos:
[E + AA + Q + AA]
[W + R]
[W + AA + Q + AA]
