Hakais most used jutsu(if he gets accepted:P)

Name:Chakra thrust lvl:1 (Charge of the wind)
Rank: D
Range:5 meters
CK: ? ( u ppl decide)
Description:User will gather chakra in his two feets.He will then release the chakra pushing it behind with greater force,making him go forward with great and sudden speed but only for a shorter range.Also if he jumps he can use the technique to push him even further making him create bigger jumps.Also it is usefull to make him dodge the incoming objects in mid-air,and if the user is falling he can trust himself upwards to reduce the damage.
Note:(can only be used once per turn)

Name:Chakra thrust lvl:2 (Charge of the storm)
Rank:B
Range:5-10 meters
CK:(don't know either u decide)
Description:User will gather chakra in his two feets.He will then release the chakra pushing it behind with greater force,making him go forward with great and sudden speed but with even greater speed and further range than the Charge of the wind.It will apear almost as a cloud of dust left behind where the user stooded but no trace of the user.It is used to travel shorter distances with greater speed interuptin enemys jutsu in a sec.

1. It is basically a tree climbing tech. so i see no problem with it. Make it 10 chakra to use.

2. It must leave a trace as it is B rank and you were there. Make it 20 chakra because it is a larger version of 1.

why 10 and 20 chakra??i tought that maximum chakra for an jutsu is 10?
