Resizing Potion: shrink, grow, and rethink combat in Minecraft
If you have ever wanted your Minecraft character to feel truly huge or sneak through a one-block gap like a tiny mob, the Resizing Potion mod is one of those niche Forge-era projects that turns size into a core mechanic. Instead of only tweaking speed or jump boost, it ties your hitbox, reach, and movement feel to potion effects, so “big” and “small” are not just cosmetic ideas—they change how you fight, explore, and survive.
What the mod actually does
Resizing Potion adds brewable potions that change your scale. Growth pushes you toward a heavier, tankier playstyle, while shrinking trades raw power for mobility and vertical play. The effects stack with familiar Minecraft systems like brewing stands, ingredients, and amplifiers, so experienced players can treat size shifts like any other potion route: plan routes, pack bottles, and pull out the right brew when a build or boss fight demands it.
Growth potion: hit harder, shrug more hits
When you go bigger, the kit leans brawler. Growth increases attack damage and knockback resistance and bumps step height so chunky terrain feels less sticky. The tradeoff is intentional: you lose a slice of movement speed and attack speed, so you are powerful in straight fights but slightly easier to kite. On servers with heavy PvP or custom mobs, that split makes size a real team-role decision—someone can be the frontline while faster players flank.
Shrinking potion: speed, jumps, and wall climbs
Shrinking flips the fantasy: you gain speed and attack speed, jump far higher, and at Shrinking II and above you can wall climb in situations where normal mobility fails. You pay for it with lower damage, worse knockback resistance, and reduced step height, so you burst around the battlefield but connect for lighter hits. It is a great pairing for parkour bases, tight caves, or mods that add cramped structures where a full-size hitbox is a liability.
Setup on Minecraft 1.12.2 (Forge)
The original release targets Minecraft 1.12.2 on Forge, with Artemis Lib as a required library—grab a compatible build labeled ideally 1.0.6 or newer from the same place you normally fetch mods, then install Forge through a supported launcher. Optional integration with Baubles adds a trinket workflow: craft an inert bauble, hold the potion effect you want, then right-click to “lock in” a constant size buff if your pack allows it. That pattern is perfect for packs where you want shrinking as a traversal tool without re-brewing every few minutes. If you like keeping Fabric and Forge mods separated by profile, dropping a resize stack into a fresh instance is straightforward when your launcher lets you browse and add files per version; some players even consolidate setups through tools that prioritize one-click profiles, which helps when you hop between legacy 1.12 packs and modern releases. If you are comparing launchers for juggling old Forge maps and newer Fabric worlds, this mod can be easily installed via the foxygame.net launcher—a convenient, flexible, and modern Minecraft launcher where you can download mods right from the menu—so you spend less time path-hunting and more time testing potion routes.
Important reality check: development status and modern picks
Resizing Potion is considered discontinued, so do not expect new balance tweaks or update trails for current Minecraft versions. If you want a similar fantasy on 1.16.3 or newer, the community guidance is to look at Extra Alchemy version 1.4.2 or higher on Fabric and pair it with Pehkui for proper scale mechanics. That route is explicitly Fabric-focused and is not expected to arrive on Forge as a port of the same stack, so plan your loader before you fall in love with a specific mod list.
Compatibility, clashes, and fair play
The README calls out several incompatibility risks. Metamorph, Morph, Lucraft Core, older LLibrary builds, More Player Models, and Tropicraft are flagged for hitbox, eye-height, or crash issues; mixing models-heavy mods with resize effects can produce jittery cameras or rule-breaking sightlines. Known issues include camera clipping near walls on Shrinking II, which can look like x-ray angles on some servers, and occasional camera oddness that is hard to patch without invasive coremods. The author also warns against pushing shrinking to extreme levels, where collision can fail and you may fall indefinitely—treat high amplifier experiments as creative-mode science, not survival progression.
Design takeaway: size as a tactical potion line
Resizing Potion is a snapshot of an era when Forge 1.12.2 packs loved quirky combat layers. It is not a permanent size slider; if you need a steady scale baseline, other niche mods were suggested historically, though support landscapes change over time. Still, for curated retro packs, the growth-versus-shrink tradeoffs create memorable moments: a giant holding a chokepoint, a tiny scout scaling a castle wall, and a brewing table that now decides who plays tall and who plays fast. Pick your loader, respect the incompatibility list, and treat the camera quirks as part of the legacy charm—or migrate to the Fabric follow-ons when your world needs fresher Minecraft updates, blocks, biomes, and mechanics.
