Size Shifting Potions
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Size Shifting Potions
REQUIRES PEHKUI
This mod runs on Quilt, Forge, and Fabric.
Size Shifting Potions adds four new potion types to the game, that allow you to change your size. These are:
- Growth Potion: Strength Potion + Red Mushroom
- Shrink Potion: Weakness Potion + Brown Mushroom
- Widening Potion: Fermented Spider Eye + Growth Potion
- Thinning Potion: Fermented Spider Eye + Shrink Potion
Config
As of v1.4.0, there is a config that utilizes MidnightLib, which has the following options:
- Toggling each potion, so you can disable them from being brewed.
- Switch the recipes from using Red/Brown mushrooms, to using Warped/Crimson fungus.
- The minimum and maximum size that the status effects can change you to.
