iv's Armor Weight
by _ivaan26_
iv's Armor Weight lowers movement speed in proportion to the total defense a character carries, so heavily armored builds move more slowly.
What it does
Movement speed drops by about 1% for each point of total defense, which slows tank-style builds that stack armor. The effect is linear, and the mod aims to rebalance larger modpacks with long progression by making early gear and mid-game armor feel more consequential. Installation needs NeoForge, and the mod is server-side only, so players join without installing it. It is released under the MIT License, not open source, for 1.21.1 only.
Key features
Speed reduction from defense
Total defense lowers movement speed, so every armor point carries a small movement cost.
Linear combat scaling
The slowdown grows in a straight line with defense, giving armor-heavy builds a predictable trade-off.
Progression rebalance
The effect is meant to pace long progressions in larger modpacks, where slower armored characters change how fights unfold.

What the author says
Very simple and light mod, it just reduces movement speed by 1% for every point of defense to make progression less linear in combat, making tank-like buils slower by definition. It aims to be just a little rebalance to have on bigger modpacks with long progression.
