Size changing potions
by Icosimath
Size changing potions adds potions that make a player taller or shorter, for a Magic and Cursed style twist on NeoForge 1.21.8 – 1.21.11.
What it does
Drinking one of the added potions changes the size of the player character, making it much bigger or much smaller. The author describes the mod as simple and effective, and it is aimed at players who want to try unusual effects. It is a NeoForge mod for game versions 1.21.8 – 1.21.11, and it can be installed on the client, the server, or both, since neither side is required.

What the author says
This is a pretty simple mod that adds 2 potion effects: Size increase and Size decrease. THey do pretty much what you think, change your size. Also, when you break a block with the size increase effect, it will explode with an appropriate magnitude. What makes this mod unique is it uses minecrafts attributes instead…
