Yes, Slashley you are right. Currently Asherah is the end game changer for water in nutaco.
And yes her name is Vohu Manah and no a perfect water team dosen't exist tbh.
You can either use Shiva AW or Asherah later. But people prefer to use Shiva AW instead.
But Vohu Manah is pretty much core from now on. Especially if you want to run Shingen with BG ex skill.
Vohu Manah+Shiva AW/Asherah+Ryu-Oh/Water Cybelle/Cythulhu+Lakshmi/Poseidon AW/Snow Raphy/Sarasawati...
