[HSR] How I beat Story Mode Aventurine Boss with Standard Banner Only Account + Build 

Just thought I'll just upload this since I still see a lot of ppl stuck at this boss even after nerf. This is actually on my standard banner only account btw, not on my whale account. Sorry it's a bit long (skill issue...lol ) Hope I can help some ppl who're still struggling... ._."

TL;DW version:
1) Outside of dice roll phase:
- M7 shield either Pela or Serval
- Don't use Pela's or M7's ultimates unless you're confident that you can break him and get your ultimate back before the next dice roll
2) During dice roll phase:
- Everyone except Nat use ultimate
- M7 shield Nat
- Nat makes sure she can tank both the dice penalty hit and the attack following right after
3) Rinse and repeat till you win
