Ultra Hard Difficulty
by klausiiiii
Ultra Hard Difficulty makes Minecraft harder by changing how blocks drop, how jumping works and how travel through the Nether and End plays out, aimed at players who find the vanilla game undemanding.
What it does
The mod changes several core mechanics at once. Blocks drop modified results, jumping behaves differently, and trips through the Nether and End bring extra surprises. Its stated goal is for players to defeat the Ender Dragon while the game keeps a real challenge throughout the run.
The mod is built for players who want a harder survival experience, and it also suits speedrun play, since the author notes a timer and a video leaderboard for better times. It runs on Forge and NeoForge, and the environment is client and server, so the server and every player need it. Files cover 1.20.1, 1.21.1, 1.21.2, 1.21.3 and 1.21.4, with 1.0.0 as the latest file for each loader. The code is all rights reserved and not open source.
Key features
Modified block drops
Breaking blocks yields changed drops, so familiar resource gathering no longer follows vanilla rules.
Altered jumping
Jumping is reworked, which the author presents as a deliberate way to raise the difficulty.
Nether and End surprises
Travel through the Nether and End brings additional events that change the expected route.
Speedrun timer and leaderboard
A timer and a video leaderboard for better times are planned as part of the mod's speedrun support.

Use cases
Hardcore survival
Players who want Minecraft to feel like a real challenge can play a full run with the modified rules.
Speedrunning
Runners can compete on a timed route to the Ender Dragon and submit their times to the leaderboard.
Who it’s for: Players who find vanilla Minecraft undemanding and want a single goal of defeating the Ender Dragon under harder rules, as well as speedrunners who track their times.
How it compares
Hard Crafting is a Fabric, Forge and NeoForge mod for 1.20.1 – 1.21.11, released under All rights reserved and not open source, and it changes crafting rather than the wider game. Item Speedrun is a Forge and NeoForge mod for 1.20.1 – 1.21.8 that is also client and server and not open source, and it centres on item-based speedrun goals. Random Item Speedrun is client-side only, open source under the MIT License and covers 1.20 – 26.3 across four loaders, so players can join without installing anything.
