This Katana does not shoot a straight shot; the shots move in a sine wave pattern, but they will true up at the middle and end of the range. Its name translates to “Sword of Poison” from the Japanese kanji “毒の剣.”
This katana was considered the best katana in the game before Build X10.3, because its DPS and range clearly beat Masamune. While it has since been nerfed, it still strongly rivals the DPS of the Masamune but stands no chance against point-blank weapons such as the Void Blade and the Sullen Blade.
Although only doing slightly more DPS than the Masamune up to 43 defense, this katana can still be one of the best due to its longer range. This katana is most efficient for godland farming as well as low-defense enemies that are too dangerous to be attacked at point-blank with the void blade or sullen blade. The player will need to get accustomed to the wavy shots, however.
It should be noted that the Sadamune outdamages the Doku completely, making it a preferable choice for DPS and straight shooting.
