Ninja Artefact

The Ninja Artefacts are a trio of three powerful rings that possess a small portion of the power of a god of yore.

Ring of Amaterasu
Named for the goddess of the sun, this Artefact gives the user the ability to utilize a wide variety of Fire Release jutsu. It also grants them the power to manipulate flames, with the exception of high-ranked Katon.

Ring of Tsukuyomi
Named for the god of the moon, this Artefact gives the user the ability to fully mend their wounds in the light of the moon. The ring also gives the user the ability to manipulate water, with the exception of high-ranked Sution.

Ring of Susano'o
Named for the god of storms, this Artefact allows its bearer to walk through gale force winds unharmed, and increases their resistance to Fuuton by twofold.
