As of SASSOT v1.1.3-1.20.1+bettercombat, this data pack is now built-in during World creation by default.
Older Worlds still require manual installation.
This additional data pack is required to properly play SASSOT together with Better Combat.
This small data pack modifies Vanilla weapon attack ranges according to SASSOT mechanics on top of Better Combat. Without it, vanilla swords and tridents will not receive SASSOT's extended attack reach.
Upon installing the above mods, please also download this data pack and install it into your worlds.
