This Katana does not shoot a straight shot; the shots move in a sine wave pattern, but they will true at the middle and end of the range.
Doku's shot pattern

It strongly rivals the DPS of the Masamune, but stands no chance against point-blank weapons such as the Void 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 efficient for godland farming as well as low-defense enemies that are too dangerous to be attacked at point-blank with the Void 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.

This katana was considered the best katana in the game before Patch 27.7.X10.3 (Feb 2017), because its DPS and range clearly beat out the Masamune. In that release, it was nerfed from its original damage range of 130-150 and its original rate of fire of 125%.

Its name translates to “Sword of Poison” from the Japanese kanji “.”
