Epic Weapons is a datapack for Minecraft 1.17+ that adds lore to your weapons as you use them. The more hostile mobs of a certain type you kill, the more the lore of your weapon develops.
For instance, as you kill Skeletons with your sword, it will become a Skeleton Slayer weapon, then progress through Bone Rattler become The Bone Mealer, The Skull Crusher and then finally The Pulverizer.
The pack is currently in an Alpha state.
