The Dokuto Swords (朧 Oboro) are a special weapon for Ayame first seen in Tenchu: Wrath Of Heaven. They are similar weapons to Ayames Tanto. The blade of the weapon is poisoned -hence the secondary name dokutō (毒刀, "poisoned sword")-, therefore making them very effective. However, equipping the swords will result in poisoning the bearer. This will decrease the baerers health by approximately 22hp, Unless poson antidote is used. The Dokuto swords have similar attack speed to the Tanto.
