Will Vodyanitsa Make My Wanderer Do More Damage?

I'm debating on pulling for Vodyanitsa since I'm saving for the Tsaritsa, but I want to know if she increases Wanderer's Damage by any significant amount?

Right Now, His team is Wanderer C4 R1 Durin C0 R1, Nicole C0, Faruzan C6

If it matters Any, I have Odette C0

Side Note: Should I also be farming the new Stellar Swirl Set? He's on his BIS set right now.
