The Logic Mod
by Wecan
The Logic Mod adds fall damage reduction to blocks, so wool, snow, leaves, soul sand and metal blocks each soften a landing by a set percentage.
What it does
Each block type reduces fall damage by a fixed share: wool reduces it by 65%, a full snow block by 50%, leaves by 15% and soul sand by 10%. Diamond, gold and iron blocks are also listed as landing surfaces. The author describes the values as a balance option for players who lack iron, and the damage figures are computed with real-life physics equations.
The mod changes only the damage a player takes on landing. It does not alter vanilla mechanics such as water drops, and it adds no physics behavior such as falling trees or floating blocks. The author states that additions should not affect other mods in a meaningful way and should not make the player experience significantly worse. The Logic Mod is client and server, so the server and every player need it, and Fabric API is required. It is released under the MIT License and is not open source, with files for 1.20 – 1.21.4 on Fabric.
Key features
Fall damage by block
Wool, snow, leaves and soul sand each reduce the damage taken from a fall by a fixed percentage.
Metal blocks as surfaces
Diamond, gold and iron blocks are included as landing surfaces with their own reduction values.
Physics-based damage values
The damage numbers are calculated with real-life physics equations rather than arbitrary constants.
Vanilla mechanics left intact
The mod does not replace vanilla systems such as water drops and does not add falling trees or floating blocks.

Use cases
Low-iron survival
Players who have little iron can use the wool and snow options as a fall safety measure while progressing.
Who it’s for: Survival players who want a fall damage option that uses blocks they already have, and server owners who want a change that keeps other mods working as before.
How it compares
Rose Gold Gear is open source under the MIT License, is client and server, and has files for 1.21 – 1.21.3 on Fabric. Diamond Nugget is client-side only, not open source, and covers 1.21 – 1.21.2 on Fabric. WaterDrop is client-side only, not open source, and targets 1.21.9 – 26.1.2, so it does not overlap with The Logic Mod's version range.

- I wanted to balance them as possible, so now they're a usefull option when on low iron cases Im working on a mod that uses real life equations to calculate damage, but its not ready now:(
