Don't go overboard or they'll be denied.

can i register a nine-tailed chakra move? Its nine tailed chain lash. The chakra forms a chain and can whip and try to capture people.

Ok maximum length of 30 ft, no abusing it or I'll declare it a forbidden jutsu

Can I have a tigram jutsu? Its called Thunder Tigram Earshot used to temporarily stun enemies (or kill if lucky [about 5% chance])

Make it a Kage lvl jutsu and make the kill chance 0.000001% or take it away altogether and make stun about 2 secs for a chuunin lvl and accepted.

I want to register a jutsu that makes wind try to slash a target, like a sword except that its long distance and of course can be evaded. I will call it wind slash jutsu.

Uhh I think there's already a jutsu like that...basically all wind jutsus are for cutting so use something better; you're a kage.

I want to register a move called bloodline seal, stops the opponent from using a bloodline for 2 posts.

I think I was mentioning 1 post of no bloodline meaning they can reactivate it after a post. Jounin lvl, 200 chakra.

But then you changed it to two posts, right? I remember you did.

Ok 2 posts then they can reactivate. For anyone confused thats the person its used on has to wait 2 posts.

i want 2 make a jutsu called fire palm;a ball of fire(resembling the rasengan)gathers in the users hand and if the user hits his target it explodes on contact throwing the target back 30 ft and burning them severly.

Accepted with this:

Downfall: Will also hit user
High Chuunin

THANKS CAN I USE IT?

Not until you are High Chuunin.
