A well equipped marksman with an interesting kit Lucius comes with a unique passive, and the ability to be played two ways. If he uses its ability too often he loses the ability to cast his ultimate for a time but ignores his targets defense and gains a huge damage buff making him a very good ranged DPS. In most situations this is preferable, but using his ultimate  removes buffs from some enemies in the game. The most noticeable instance of this is when facing Guild boss 2, where whilst hard to manage, can temporarily remove Aegis stacks from the boss.
