I'm a beginner building a water team with Rudra, currently rank 18. There's so much to do in this game that I'm a little lost - what should I be prioritizing my AP for? I was originally just doing story mode but realized I can do standard raids/poke Ragnarok raids (in hopes of SR weapons) and standard mode for the event advent battle (someone suggested farming materials to get raid gacha tickets). I also feel like I should be doing the element caves since I'm starting to have SR kamihime's stuck at level 30.

Thanks in advance!
