Sorry for the late reply.
"Nicely done, Yukihira. Now, we will move on to the next techniques. The first technique starts off by forming several hand seals, and focus your Rain based chakra in all the rain drops that are falling up to Mid range around you. This allows you to make all the rain drops, pitch black in color. This makes the rain invisible to the naked eye, which makes it a very powerful technique, as all the Rain techniques you perform afterwards will be invisible. This makes it a nice technique to start off in a battle, and could possibly lead to you winning the battle. Use it to destroy my clone."

"After that, use your Rain based chakra to create a large dragon made from the rain clouds. This dragon can swoop down from the sky, onto the battlefield, and the dragon is capable of firing a spiral spear of rain from anywhere on its body, once per post. The dragon can also direct a small rain storm towards the opponent, and rain techniques can also be used from the dragon itself. A very versatile technique, so use it in a combination against my clone."

"Then, use your Rain based chakra to create an advanced form of the Rain Spear technique. This technique starts off by condensing a large amount of Rain to a single point, from which spears of water can be formed. The spears at any time can be called down at any time, with a single hand seal. The difference with these spears are that they are in a corkscrew shape, and can drill into the opponent and can be manipulated to either widen or sharpen, so it will cause more damage. These spears stay spears for up to two turns. Then they change back to rain. Use it on my clone."
