Lucian in the early game when in lane is the thought of the matchup, For example on an AP mage like Akali as my first game with Lucian, the matchup is with Teleport it is an aggressive Akali player with it, so Lucian can counter the total damage Akali can put. First, I have to prioritize long range-minions when last hitting to at least do a freeze or shove. Second, Use Q and E to check where Akali would be either roaming or in a teamfight. And lastly, get blue ward ASAP since I would scout real hard. This is the summary of the whole matchup since I will pop off.

Manamune into Muramana is the core part of Lucian's mana sustain.
1 Is that it gets value everytime you scale into another item or certain items.
2 Lethality and crit items benefit his ad and most of his skills to Relentless Pursuit and Ardent Blaze etc.

Thank you for reading as this Lucian Guide will come to be finished as the season goes on. I am Gdmmm or Rafael as a Lucian Main.
