Wait, so for Iron Wire Fist, the description is a bit confusing, along with the range assigned to it. Is it that when performing this technique you throw a punch that releases the wire, causing the wire to strike the target and deal damage? Or is it that the strikes you land with the wire wrapped around your fist pushes them out toward mid range for whatever reason?They have their upsides, but, as mentioned, also a downside in their chakra cost. That is, however, the rule more than an irregularity. The next two lack that downside, but have their own issues. The first one in requiring a tool and the second one in assuming a speed advantage plus putting the user in a position where evasion is more difficult than absolutely necessary.
Consider them, as you have the others, thank you.
( Testsu Sen Genkotsu ) - Iron Wire Fist
Type: Offensive
Rank: B
Range: Mid
Chakra cost: N/A
Damage points: 40
Description: By wrapping ninja wire around their fists and controlling their breathing the user is able to deliver precise and deadly strikes that are able to knock targets back several meters.
( Chouyaku Kage Dageki ) - Jumping Shadow Strike
Type: Offensive
Rank: B
Range: Short
chakra cost: N/A
Damage points: 40
Description: The user appears below a target in a low stance, striking at the pressure points in their inner thighs. A successful strike should cause an opponent to collapse, allowing the user to deliver a series of rising punches.
When using this other technique, it'd probably be best to attempt to appear behind the target to make it more difficult for them to counter. As you mentioned, positioning yourself in such a low stance in front of them leaves you vulnerable to attacks, particularly knees or leg strikes.
