Prioritize maxing Piercing Light as it's your primary ability for harassing the enemy lane champion.
Piercing Light also combos well with Lucian's passive Lightslinger, because casting an ability procs the passive causing him to attack a target twice.
LoL Lucian players will likely find him to be a dynamic champion to build out properly. You will notice that his build is modified when he is fighting either well-rounded or specialized team compositions, meaning you shouldn't choose the same Lucian build every single round of League of Legends
The most important items to use in your champ's build include: Navori Quickblades, Bloodthirster, and Rapid Firecannon. Those who added these items in their kits had a higher win rate than players who tried for other item builds for Lucian. Similarly, if you are trying to beat a mixed enemy team composition, you should really consider grabbing yourself the Precision, and Sorcery runes. In recent games, he won the largest percentage of his rounds when using these runes.
