Genshin Impact has a lot of four-stars that, over time, may have been put on the back-burner or forgotten. But Genshin Impact's Noelle doesn't need to collect dust -- she can be as good as Arataki Itto in some circumstances. She's a solid DPS, though a greedy one (meaning, a DPS who requires all talent level-ups and needs a lot of on-field time.) As a unit who scales off DEF, it's important to get her all the way to 90 so that her base DEF gets as high as it needs to.
