Alright. Because of the high amount of calories you'd burn to create the chakra in order to expand your arms multiple times in a quick succession, that seems like a fair drawback. You'd have to recover from the loss of calories.
I did come up with another question, I should have waited with the previous post >.>
( Mizudan Suisha ) – Ballistic Waterwheel: The technique that lets you absorb up to B-ranked water techniques. Does it allow you to absorb every single water technique up to that rank, because techniques like the Water Dragon are a huge amount of water and others like the Rising Water Slicer are mentioned to be extremely sharp, cutting through the ground?
I mean, the technique could be described as following when used: "I channel my chakra into your B-ranked or below water technique to drive out your chakra. The jutsu becomes pure water with no real power or shape (losing its cutting abilities) behind it that allows me to drink it."
Would that suffice?
