Shrink and Growth Potions
Ever wanted to tower over your friends or turn a troublemaker into a tiny speck? The Shrink and Growth Potions add-on makes that possible with a pair of potions that bend one of Minecraft's newest mechanics to your will. Built on the scale attribute Mojang exposed in 1.20.5, this mod turns a clever server trick into a full potion system anyone can brew, throw, and shoot.
What Is the Shrink and Growth Potions Mod?
This add-on introduces a Potion of Growth and a Potion of Shrinkage. Drink one and your character's scale changes instantly, letting you loom like a giant or sneak through gaps as a pocket-sized version of yourself. It is a lightweight, MIT-licensed project developed by DerexXD, with the mod icon credited to Potioncraft.
The original idea came from a survival server where shrinking and growing were used as playful punishments for hackers and griefers. Messing with scale turned out to confuse hacked clients and fly cheats, so the effect doubled as a harmless prank and a soft anti-cheat. Players enjoyed it so much that the mechanic was rebuilt as proper potions for everyone to use.
Potions, Splash Variants, and Tipped Arrows
Everything in this add-on revolves around flexible ways to apply the scale effect, whether you want a permanent change or a short-lived joke.
- Potion of Growth — drink it to increase your size and reach.
- Potion of Shrinkage — drink it to become smaller and harder to hit.
- Splash potions — throw them to affect other players or mobs in an area.
- Tipped arrows — shoot the effect at range for precise, sneaky hits.
- Temporary effect options — upcoming potion effects can make growth or shrinkage wear off after a set time.
The splash versions are the highlight for multiplayer chaos. A single well-aimed throw can shrink an entire group, while tipped arrows let you tag a fleeing player from a distance. Because the effects hook into the vanilla attribute system, they interact cleanly with the rest of the game rather than feeling bolted on.
Supported Minecraft Versions and Loaders
Minecraft 1.20.5 and Newer
The scale attribute only exists from Minecraft 1.20.5 onward, so that release is the hard minimum for this add-on. If you are running an older world, you will need to update before the potions will function. The mod is distributed as a Fabric mod, so make sure Fabric Loader and the matching Fabric API build for your game version are installed before you begin.
Checking Compatibility Before You Install
Because Mojang occasionally adjusts attribute behavior between snapshots and full releases, always confirm that the build you grab matches your exact game version. Loading a mismatched file is the most common cause of crashes, and it is an easy mistake to avoid with a quick version check.
If you would rather skip manual file juggling, the foxygame.net launcher handles the busywork for you: it lists Shrink and Growth Potions in its add-on catalog, matches the correct build to your installed Minecraft version, and keeps everything updated automatically after each patch.
How to Install Shrink and Growth Potions for Minecraft
Getting the add-on running takes only a few minutes if you follow the standard Fabric workflow.
- Install Fabric Loader for your Minecraft version.
- Place the Fabric API jar in your mods folder.
- Download Shrink and Growth Potions and drop the jar into the same mods folder.
- Launch the game using the Fabric profile and confirm the mod appears in your mod list.
- Brew, throw, and shoot your first potions in a test world before using them on a live server.
On a multiplayer server, remember that every player who wants to see scale changes correctly needs the mod installed on their client. Server owners should also confirm that the mod is permitted by their hosting provider's rules.
Why It Belongs in Your Modpack
Few mods offer this much entertainment for such a small footprint. The Shrink and Growth Potions add-on gives you prank tools, mini-game potential, and a genuinely useful utility for map makers who want variable player sizes. Whether you are shrinking a friend mid-race or building a giant-versus-tiny arena, the possibilities are immediate and endlessly replayable.
Grab the mod, brew a batch, and see how quickly your server turns into a battlefield of giants and gnats.
