Which mods do i need to improve?

There really is no minimum gear level or mods. U want Echo and 5's at 45% cc, CS has enuf cc already, w/ as much offense stacked as possible. cc/cd sets and cd traingles. U want Cody loaded for speed. The more the better and a cd triangle. U want Leia at 60% cc w/ as much offense as possible. Offense arrows on everyone but Cody. Offense crosses on everyone but 5's (he gets potency). Speed arrows and speed secondaries DO NOT MATTER on anyone but Cody.

Last week was my 1st solo p4 w/ Princess Zody. Zetas on Cody and 5's.

The closer u get to what I have listed, the closer u r to soloing for 11 mil and change.

Cody needs to be at least at 200 speed.
A zeta on Leia helped me tremendously. My damage went from 2m to 7m(as my current record), I usually average 6m(which is about 50% of the phase), if the RNG is really, really, really, really bad(by this I mean I miss like 3+ topples, because one of the cannons somehow dodged like 2 attacks) then I might go as low as 40%, but that's very rare. Zeta on Fives isn't bad either, but I'm honestly not a big fan of it.
