Libra weapons

The Libra Gold Cloth has the unique position of being the only cloth with full-on weapons. The Cloth holds two Swords, two Shields, two Tridents, two Tonfas, two Nunchuks, and two Sansetsukon. Each weapon is highly powerful, able to do things that even the combined power of several Gold Saints could not do. It is said that they can even pierce stars.

It must be noted that Athena forbids her warriors from using weapons. However, if justice is threatened, the Libra Saint can judge if the use of his Cloth's weapons is necessary.

Thus, Dōko fights mostly with his cosmo, using (or doning) only his weapons when there is no other way to defeat the enemy.
