GetsuFumaDen: Undying Moon
Patch Notes V0.4.10



New Additions



  • Added the new main weapon, Whip. A total of five variations are available.



    Whips have the longest range of all main weapons, allowing you to deal significant damage to distant enemies with ease.
    Also, you can increase the power and range of their unique actions by charging them.
    Since it rewards technical playstyles, pay attention to your positioning to maximize the advantages you get out of this weapon!
  • Of the five Whip variations, two will be unlocked by default.

  • With this addition, Whips, Whip Fragments and the diagrams for Beastkiller Whip, Poison Whip Adder, and Onitsuta, the Bloodthirsty Chain will drop from treasure boxes and defeated enemies.
  • Added the new difficulty "Apprentice".
    Difficulty can be changed at the Training Statue or when starting a new save file.
    Although it is more accessible than the "Commoner" difficulty, there are less stages you can travel to.
    While item drop rates are the same as "Commoner", interruptions (random encounters) will not be triggered when travelling between stages.
  • Controller vibration is now available. You can enable this feature in the Options menu.
  • Added the new Secret Art, "Weapon Rack Order". Through unlocking and enhancing "Weapon Rack Order", a maximum of two new weapon racks will be added to the Getsu Clan Estate.
  • (Community) New options have been added for adjusting Blood Animations.
    Not only can they be toggled on or off, they can be set to one of four available colors.
