Forum:Difference Iwa no Yoroi and Doton: Domu

what is the difference between Rock Armour and Earth Release: Earth Spear ??? i confused about the pro and cons?? they seem so similar....

Their appearance for one. And the names. One technique uses internal chakra flow and the other manifests the technique externally forming a casing as opposed to Kakuzu's hardening of his skin.--Cerez 365 ™(talk) 14:17, May 6, 2012 (UTC)
