I'd like to issue an apology for taking so long to reply, had a rough patch in real life, but I am back now. So let's do this!
Seeing as Unalaq could figure it out, Dean was happy. They could go on, and because Rain is one of Dean's favorites, he was always excited to teach it to a new student. Without wasting any time, Dean looked towards Unalaq with a stoic expression on his face. They had to go on now, the training has started.
"Alright, now that it is raining, we will begin. My method is as follows, I will explain the technique to you, then I want you to perform the technique against my clone, give me at least 2 advantages and disadvantages of said technique, how you would use it in battle, and if you have any questions, don't hesitate to ask.
Now for the first technique you must form your Rain chakra by combining your Wind and Water natures. After doing so, gather your Rain chakra to your palm of your dominant hand. This would cause the Rain drops to be attracted to your hand. Once they are attracted, you will use shape manipulation to form the Rain into a spherical pressurized shape, like an orb. This orb of rain can then be launched towards the opponent, where it can deal minor damage like blunt impact, hitting the opponent back. Use it on my clone."
Dean creates a clone that runs towards Unalaq.
