fought Phantylia a few days ago.
characters I used:
Bailu level 70
Serval level 70
Qingque level 70
Jing Yuan (trial character) level 78
recommended was level 76, but it's fine using level 70 characters. Just need to have them properly equipped. Trace and light cone levelled properly as well.
got lucky, won it on the first try.
phase 1 and 2 are easy. Third phase is where things heat up (no pun intended).
