It would be cool to have a water sorcerer I always like the water element
Like for the water sorcerer's passive his body is like fluid like juvia from fairy tail no physical weapons can't hurt him arrows can't hurt him they would just go through the water part of him be cool to have the water effect also on him when he's taking the hit the only way to counteract it if he gets hit by like a fire arrow or fire bolt and since his body is made of water he'll take steam damage for two or three turns if hit with electricity arrow or any electric spell his body hardens so he could take physical damage for two or three turns or hit with a ice attack or ice arrow body becomes Frozen and if it gets hit by a physical attack he shatters does it kill him but just there for the effect and it hit by fire the ice melt and he regenerate back into his form but hit with anything liquid like acid or oil his body soaks it up and his next water attack he shoots it back at them or if the oil is inside of him still and he gets hit by a fireball he blows up taking blast damage
And if u can think of any water spells that be awesome or message me and we can come up with some ideas
