About this Mod

Sword and Sheath

Overview

This data pack/mod adds a stylized version of the legendary cursed katana of Muramasa from Japanese legends. It can be found within a new structure called the dilapidated temple which generates in cherry groves, jagged peaks, and taiga forests.

Beware of the curse! If the katana does not claim a life in time, it will take the user's instead.

Features:

Slice: a large cutting attack, left click and swipe
Sheath Draw: a flurry of cutting attacks, hold in offhand for a second, then swap
Dodge: grants I-Frames, tap crouch
Parry & Guard: blocks incoming damage and retaliates if timed right, tap or hold right click
Curse: deals true damage to the user after a period of time without killing, resets upon killing an entity with the katana

To instantly obtain the sword:

/function weeb:give_sword

To locate the structure:
