Cursed Seal of Earth

is one of the strongest of Orochimaru's cursed seals, the other being its counterpart: the Cursed Seal of Heaven.

Usage
It consists of three slightly curved lines, which spread in a rip-like pattern. The seal is located of the upper portion of Kimimaro's chest over his manubrium. When the first level is activated, the seal expands and lines spread all over Kimimaro's body in contorting and parallel lines. When the second level of the seal is active, Kimimaro takes on a dinosaur-like appearance complete with a tail. Several large bones also protrude from his darkened skin. This cursed seal is particularly strong even amongst the other already powerful cursed seals with Kimimaro being the only known user and with the Cursed Seal of Heaven standing as its only equal. Like all cursed seals, Kimimaro receives increased chakra levels, physical capabilities and his ninjutsu skills become more effective when the seal is active.
