HELP WITH ISO

Heyo Guys im kinda broken with iso and i have upgraded my Spidey2099 to Rank2 today but now i wanna lvl him up and suggestions to grind iso?

theres a daily iso field quest

Duping 4* champs is the best way to farm ISO. Focus on content that offers 4* shards (story, EQ, SQ, solo/alliance objectives, etc.).

4/5 stars are the best source.

Have you done the lower monthly sq yet? That’ll give you some shards
