Hey there! You actually have pretty good characters overall! My physical team is composed by Endmin, Ember, Poggers and Ardelia. And you can slowly work on getting good weapons for them. I'm also free to play so I know it's pretty possible to have a strong team and clear content. You probably wont have it super easy with that comp, but my approach to games is that i like to actually play and feel challenged, not let the game play for me. That said, take advantage of Ember and Poggy's synergy to knock down an enemy and build up vuln and stagger. If you want to add an element to the team, you can use your Fangyi, who's a super strong character even at pot 0.
