Ok, so this jutsu is very nice. Two hand seals and focus your chakra into a water attack you created within the same turn, then it becomes bigger and stronger gaining twenty points. It happens to only one jutsu and activates pretty quickly from my understanding. Not a hard technique to understand, but VERY useful. Thanks again!
I'd probably surround my opponent in the middle of a Suiryudan made of water then make it stronger with the expansion, making their previous defense a failure due to the increased might of the Suiryudan!
