Rain Tiger at Will Technique

This jutsu needs a range for one described in meters likely, currently you can vague it to say the jutsu can reach all across the world which makes little sense for the cost of this jutsu and is extremely powerful.

"When the rain is obstructed by a chakra belonging to someone not of the village,"

I dont see the reason as to why this is limited to someone whos not of the users particular village. Though I understand canonly it was described that way, there's no real evidence that can explain why everyone in the village is excluded from this techniques detection without personally memorizing every single chakra signature in the village. Unless for some reason the user has memorized every signature in the village, then a person should be able to discern if it's an "intruder", though that's achieved mainly through IC development. I'd like to request you relinquish that wording and utility in the jutsu, especially as those who are unaffiliated are in a grey zone as to who exactly should be effected by this.

Though another way to go about balancing the function of that jutsu and reason with how it was utilized in canon is possibly stating that all chakra signatures present upon the first post of rain droplets are immune to the senses of the jutsu in that particular time in using it. Any signature that enters the preexisting chakra pool will be detected, though if someone initially within steps out and wishes to reenter they'll be treated as an intruder to the current state of the jutsu. That's an option as well.

I feel personally that this jutsu should also refrain from being centralized on the users location in the context of consistent movement, so a raincloud that constantly follows the user and that the raincloud should dissipate and become numb to relaying sensations to the user once they're a certain point away from the jutsu site.

I'm not sure it's fair to allow such a technique to consistently relay such information in likely a wide range without some sort of cost per post to keep the jutsu working properly, especially as the jutsu can essentially be indefinite. I'd ask you fix it.

There are a few other potential issues with the technique, but it's better to wait until the main ones are touched on to see the state of the jutsu then before moving forward. If you have any issues pm me or request someone else to come check this app out.
