Ineffa was the very first character from the region of Nod Krai to debut in Genshin Impact, and she might make a good addition to your team comps if you find that Fischl just isn't enough.
If you want to see her robotic abilities at their best, you'll need to go hunting for all of Ineffa's ascension materials and skill materials first, which includes stocking up on Glowing Hornshrooms in Natlan. Probably best not to ask what a robot needs with all those shrooms.
