g12 zbossk (215) , g12 Boba (208), g11 Aurra, g10 Dengar, g10 cad.

Level 6 was very easy for me before 7* Aurra and Cad, but I understand there is a SIGNIFICANT jump between 6 and 7. I can gear them up if needed, I have some stuff saved but have other priorities I would rather focus on.

Definately. I posted somewhere here in events what I had last time for 7* and it was less. Granted I had Jango which is a slightly better damage (especially 2nd skill). But my gear levels were less. It's about the turn order and getting the first turn with right rng, all alive etc
