Mendelevium
by BJC95
Mendelevium is a Forge 1.20.1 optimization mod whose items and effects are built around lag, TPS and glitch tornado events.
What it does
Mendelevium is aimed at the game's tick rate: its author notes say it lags out the TPS on purpose, so it suits adventure and cursed play rather than performance tuning. It runs on client and server, so both sides need it. The only file is a Forge build for 1.20.1, published 2024-08-28, and it is released under All rights reserved, so it is not open source.
Key features
TPS lag effect
The mod slows the server's tick rate, making the game stutter for everyone in the world.
Lag Reset item
A crafted item called the Lag Reset item is listed in the author notes as a way to undo the slowdown.
Glitch tornado loot
Looting seven glitch tornados, along with the starting inventory, is part of how the mod plays out.

What the author says
DO NOT USE ON WORLDS YOU CARE ABOUT! IT WILL CORRUPT! A mod made as a joke to lag out your game. Based off Sodium and simialar mods. There is two new items you get, the lag detector and three lag resets. Your game will extensively lag and crash unless you use one of these to reset the varible.
