Ultra Hardcore Attributes
Ultra Hardcore Attributes is a NeoForge game mechanics mod that cuts player health, reach and movement and makes every fight and fall more dangerous.
What it does
Players are limited to five hearts in total, half the vanilla amount, so a single hit or fall carries more risk. Water sinks the player, and rivers and oceans can be deadly. Catching fire lasts 30 seconds, and lava is a death sentence.
Combat and movement change too. Bare fists deal only 0.2 damage, so fighting mobs becomes slow and painful. The jump key performs a short dash instead of a normal jump, Jump Boost II barely lifts the player over a trapdoor, attacks only reach a short distance, and walking is a little slower than usual. The mod is built around changing basic attributes to make survival much tougher.
The mod runs on the server alone, so players join without installing it. It is published only for NeoForge, for 1.21.8, and the license is All rights reserved, so the code is not open source.
Key features
Halved health pool
The player has five hearts in total instead of the usual ten, so damage from any source matters more.
Harsh fire and water
Fire lasts 30 seconds once ignited, lava is lethal on contact, and the player sinks in water.
Weakened combat
Empty-hand attacks deal 0.2 damage, and the reach of attacks is cut to a short distance.
Altered movement
The jump key triggers a short dash, Jump Boost II gives only a small hop, and walking speed is lowered.
