Real Knife (Undertale)

by PHDev

Real Knife, an Undertale-inspired Fabric mod for 1.20.1, adds a progression of knives whose strength grows as a player's LOVE level rises from 1 to 20.

FabricClient and serverAll rights reserved1.20.1

What it does

Players begin at LOVE 1 and earn EXP by defeating living entities, with rewards scaled to each enemy's maximum health. Stronger enemies give more progress, and enough EXP raises the LOVE level. Excess EXP carries over when several levels are gained at once, and LOVE level and EXP persist after death and disconnection.

The weapons form a chain: a fast, low-durability Toy Knife that cannot break blocks, a heavier Worn Dagger with more damage and durability, and a Real Knife that is awakened at LOVE 20. Abilities include phantom attacks and automatic parrying of projectiles. A custom HUD beside the hotbar shows the current LOVE level and progress.

A custom advancement tree follows the Undertale theme. Some advancements reward obtaining the Real Knife, defeating specific creatures or bosses, and reaching progression milestones, and some stay hidden until completed. Real Knife runs on client and server with full synchronization, and the mod requires Fabric API. Better Combat, Farmer's Delight Refabricated and Punchy! are optional companions.

Key features

  1. LOVE progression

    A level system from LOVE 1 to LOVE 20 makes stronger knives and abilities available as EXP accumulates.

  2. Evolving knife line

    The Toy Knife, Worn Dagger and Real Knife each hit harder and last longer than the one before.

  3. Phantom and auto-parry abilities

    Knives can launch phantom attacks and automatically intercept incoming projectiles.

  4. Custom HUD

    An Undertale-styled display next to the hotbar shows the current LOVE level and progress toward the next.

  5. Advancement tree

    Custom advancements reward obtaining the Real Knife, defeating bosses and reaching milestones, with some kept hidden.

Questions

Does Real Knife need Fabric API?

Yes. Fabric API is a required dependency, so it must be installed alongside Real Knife on Fabric for 1.20.1.

Do players and servers both need Real Knife?

Yes. The server and every player need the mod installed.

Is progress kept after a player dies or disconnects?

Yes. LOVE level and EXP persist after death and disconnection, so a player resumes at the same level.
