Enhancing seal: A warrior's blessing

Enhancing seal: A warrior's blessing
This is a special kekkei genkai only avaliable to the members of the Minaki clan.It requires these things: User must be a member of the Minaki clan,user must attain the special enhancing seal from the clan head chief and user must have precise chakra control.

How to get the seal
In order to get this prestigious seal,the user has to be very lucky as it is only passed from generation to generation and only 3 people in each generation will get the seal.Hence, candidates who want to get the seal must compete in a friendly tournament.The top 3 winners will get the seal sealed into them by the clan head chief.

Effects
This is a powerful kekkei genkai.When activated,the user will gain a huge amount of chakra,as much as 8 times that of a normal sage.It also gives the user immense strength and speed.Also the user will do a lot more damage than before.The user will be so powerful that,he/she could easily destroy a kage or a few S-ranked ninja.

Weaknesses
However,if the user does not have excellent(almost perfect) chakra control, the seal could backfire when activated.Instead of giving chakra,it could drain the user's chakra,speed and strength in a matter of seconds.Hence,excellent chakra control is needed to perform this seal and for it to benefit.
