The first step of resisting Saturn is figuring out his ability. Remember Apoo?

His ability seemed overpowered and unavoidable. Turns out it is rather easy to deal with it.
Once you know how to counter it. The same will apply here.
The stare ability could work exactly the same as Apoo's so it would come to dodging/blocking instead of willpower resistance.
The paralyzing ability could be physical, he is partly a spider and Sanji has already been tangled in a web once.
This could be the same, they are probably not noticing the webs. Or it is some forcefield of DF that could be countered by Haki.
I dont think Zoro and Saturn will share any panels because all of it is saved up for the God of Finance.
Whatever can occur against Saturn, will occur against Venus.
