Soul Knife
Adds a unique soul blade to the game whose power grows with every creature slain!
Weapon Crafting

How It Works
Initially, the blade's damage is only 3 units (1.5 hearts), making it quite weak at the start. However, its main feature lies in the leveling mechanic - each living creature killed (whether it's a chicken, zombie, or any other mob) increases the damage dealt by 1 unit.
Weapon Evolution

When the blade reaches 1003 damage, it undergoes a transformation. The weapon's appearance changes, becoming more "bloody," and its damage becomes infinite. At this stage, the blade gains a special ability.

Special Abilities
At maximum development level, the blade gains a powerful area of effect. When right-clicking, all nearby living creatures (except those tamed by the player) receive 13 damage from a magical slash.
Progress Tracking

The current weapon damage can be determined by enchantments: base damage equals (Soul Sharpness × 1) + (Super Soul Sharpness × 10) + (Ultra Soul Sharpness × 100) + 3. When reaching 1003 damage, the value displays as infinity.
This weapon offers unique gameplay with long-term development, transforming from a simple knife into a legendary artifact with incredible power.
