Speaking of the water tower, floor 10 will ask for 2 defenders. By then thunder will have access to 4 defenders in tota; 2 SSR/1 SR/1 R. Everyone should at least have the R, Perun, via gem gacha. The sticky point is that if you want to clear 2 defenders and thunder only in one go, you need to have rolled Kingu, Raikou, or Athena. And it's very possible to have never rolled them (as I sure as hell haven't).
