Moon Star, Yep haha! Her dash (and well as Mona's) are unique and pretty fast (but not as fast as Sayu's dash lol).
Ooh, that Thunder Manifestation! I remember beating that boss in the Seirai quest and ended up hating it tbh, doesn't help I used Childe to defeat said boss because I didn't have any good ranged characters since most of them are underlevelled at first lmao and yeah I agree with you about the damn Hypostases (or should I refer them as elemental cubes haha), and same- I just wanna kill them just so they could die. >.<
Ikr? Although there are fragile resins but I didn't wanted to use them 'till it's finished unless I only used once or twice due to urgent farming for whatever materials are needed for my team. I kinda lowkey wished Hoyoverse should've just given more than 2 or 3 materials. :B

Rakuyo, Thank you! (As I typed before planning to farm her ascension material at the same time haha)
You're right, some people do wanted to clear Spiral Abyss for stars/primogems and seeing it just makes me feel rather demotivated to do so as I find myself almost raging so hard at some abyss floors (I'm looking at Floor 10 to 12 *glares at said floors*) which I know it's not good for me to get too emotional on a game. ^^;
Yeah, I think weapon and talent materials are probably more worth it than artifacts because RNG god says "F you, no good or decent main or substats for you" apparently.
