I completed Act 1,2,3 with these teams:

TEAM 1

Rebecca (main), Truffle, Psyche.

Geniemon for sanity recovery.

Use Rebecca to spawn jellyfish 🪼 and use ultimate skill if need quick points. Watch the progress bar and refrain from using skills when doing good. This helps maintain her sanity so we can enter next level full.

For the last boss fight against Psyche, I found it helpful to trigger the weakness as often as possible. It helped finish it within the time limit since my characters are only level 70.

TEAM 2

Lisbell (main), Phoxhunter, Fina.

Geniemon for attack% bonus.

Enter ultimate with Lisbell and swing sword at everything lol Easy clear.

I didn't use any special wedges or anything. Just the regular setup 👍🏽
