How to Get 4000 Points on Day 2

Use Melt and Pyro Swirl Reactions For Round 1

Use Ayaka and Sucrose in tandem for Round 1 to create Cryo Swirl and keep applying Cryo to enemies! Afterwards, use Bennett to support Dehya's Pyro Attacks and trigger Melt Reactions.

Keep an eye on the active brew buffs to see if you need Sucrose to Swirl Pyro or Cryo more, and gather enemies easier at the same time.

Use Vaporize Reaction in Round 2

For Round 2, Yelan, Xingqiu, and Xiangling support Hu Tao's damage! Activate Yelan, Xingqiu, and Xiangling's Elemental Skills and Burst before using Hu Tao as the Main DPS and trigger Vaporize.

Use Freeze Reaction for Round 3

The best team for Round 3 is a Freeze team! Use Ayato and Sucrose to apply Hydro to the enemies, while Ganyu and Layla both provide generous Cryo application

Ayato can deal the most attacks with his Elemental Skill while Sucrose can help generate energy. You can also use other variations of a Freeze team that you're most comfortable with!
