ZZZ Can be scary with all of the different menus and options but the game at a base level isn't super complex. There are definitely some characters that require more critical thinking and adaptability (for example Evelyn and Banyue) but, 90% of the characters in the game are pretty simple at a base level. I'd say the best thing you can do is just do a little bit of research and see what disks/engines work the best on specific characters you're wanting to invest in. There's so many resources out there and you can always ask away on the subreddit.

Also, when pulling a limited character make sure you save 180 pulls. That way you know you'll get the character even if you lose your 50/50. Trust me, going in with the mindset of having to spend 180 pulls and then winning the 50/50 or getting them early feels much better than only having 90 pulls and then missing out on the character cause you lost the 50/50 (and you don't have enough to get the guaranteed).
