Lemuen banner

Lemuen is a powerful sniper in the purest sense of the word. She hits ridiculously hard, and is one of the few Physical damage dealers that can do meaningful damage against pretty much any hard target. She's a great unit worth investment, with two powerful skills, but unlike her sister, there's a lot more overlap between them with less absurd utility (pretty much just her pseudo-global range). While Lemuen is still a strong M6 consideration, you can largely get away with just doing one of them, although the choice isn't as clear as it is with many units. If you only plan to do one skill, again there isn’t a clear cut answer, but for general use, I would lean towards her S3. You give up some ST ceiling compared to her S2, but you gain a more well rounded skill. She basically charges up, aiming at a target for each ammo, then dumps them all at once. It deals heavy splash damage that allows her to do more than just snipe the big targets, and she doesn't give up a lot of that ST ceiling to do it either. S3 also has significantly higher DPS while S2 can be quite slow in comparison. Mastery on her S3 is nothing too crazy, but DPH is Lemuen's highlight, and it does make a big difference
