Real Knife: Determination

Real Knife: Determination is an Undertale-inspired mod for Minecraft Forge 1.16.5.

Real Knife: Determination adds the legendary Real Knife, Chara's Locket, Determination mechanics, and Chara Mode.

The mod is centered around Determination and LV progression. The stronger the player becomes, the more powerful the Real Knife grows.
