Well Ill use;
(Ensan no Kouu)-Acid Rain
Rank:S
Type:Supplementary/Attack
Range:Short-Mid
Chakra cost:40(-5 per turn to keep active)
Damage Points:-10 each turn or as long as the user has this jutsu in effect
Descripton:A powerful ninjutsu that laces the clouds with a large amount of poison elemental chakra to change the structure of the rain. The end result is a storm that does not rain water, but instead rains a powerful acid that can eat through most materials. Unfortunately, skin is not one of those materials. Instead of instantly eating through, it causes skin to instantly blister and slowly dissolve in a most painful way.
(Amagasa no Jutsu)-Umbrella Technique
Rank:B
Type:Supplementary
Range:Short
Chakra cost:20
Damage Points:N/A
Descripton:A helpful technique for staying dry in the rain. After a few short handsigns, the user can create an invisible umbrella by extending their arm over their head and holding an open palm towards the sky. This "umbrella stops all rain, but cannot stop jutsu that take a more solid form like the Rain spear technique. This technique was actually made to stop the acid rain technique and other average falling rain techniques from touching the user.
Now I put a seed in my hair and since its raining it blooms instantly.
