Hashirama and Tobirama both said they had there limits when it came to the clones. I though Edo Tensei bodies had Unlimited Chakra, so how could they have a limit.. Anyone?
they have unlimited chakra supply but they have their own individual chakra levels. the edos have unlimited chakra supply in the sense their chakra gets automatically revived without eating food but they have the same chakra level when they were alive.
