To be honest your element may be water but that doesn't necessarily say that you can only use that element. before you say what uve just said try to figure out which element ur comfortable with and more into. it takes time 2 get that answer, becuz maybe u can do something with water that someother Hydrokinesis person can't so it's all a mystery 4 now. but ull know when ur ready. Oh and you CANNOT create water you can only move it so u have to be a water source like a lake or even have a bottle of water.So before you get 2 excited remember you can't make water balls but or etc. if you wanna do water balls and stuff like that look up Aquagenetics or Hydrogenetics. First study on water and make bonding with water THEN come back and ask the question.
Much Luv & Blessed Be,
