About this Mod

BackGround


"Here we are!"

Bring the ultimate weapon of destruction from Undertale straight into your Minecraft world. This isn't just a simple sword retexture; it's a carefully crafted mod designed for maximum satisfaction, nostalgia, and absolute power.


⚠️ WORK IN PROGRESS: HOW TO OBTAIN

Currently, the Real Knife is an endgame/god-tier item obtainable ONLY via the Creative Inventory (inside the Combat tab) or commands. > Because this is such an iconic and overwhelmingly powerful weapon, I am still designing a balanced and worthy crafting recipe for it. The mod is actively in development, so stay tuned for future updates!
To get it now, use:

/give @p undertale_real_knife:real_knife

KEY FEATURES

  • 💥 Absolute Power: Deals an absurd 999999 damage, instantly obliterating anything in your path.
  • 🗡️ Custom 3D Model: A high-quality, pixel-perfect 3D representation of the Real Knife.
  • 🩸 Sinister Sweep Attack: Features custom red sweep particle effects when attacking multiple enemies, true to the Genocide route.
  • 🎵 Immersive Audio: Experience the classic Undertale slice sound effect with every swing.
  • 💯 Iconic Damage Indicator: Displays the classic red "999999" pop-up floating above your target when you strike!

🤝 SEAMLESS COMPATIBILITY

The Real Knife is built to play nicely with the Fabric ecosystem out of the box:

  • 🥊 Punchy! Native JSON support. Equip it to get smooth, dynamic first-person animations! (Note: If using alongside Better Combat, ensure "bettercombatCompat": true is set in your Punchy config).
  • ⚔️ Better Combat: Fully data-driven weapon attributes. The Real Knife acts as a "Dagger", executing lightning-fast attack animations and combos.
  • 🍅 Farmer's Delight: Features universal Fabric tags (c:tools/knives). Yes, you can legitimately use this weapon of mass destruction on a Cutting Board to slice your cabbages!
