⬇ Download on ModrinthUltra Hardcore Attributes Think Minecraft is too easy? This mod will make it brutal. Ultra Hardcore Attributes makes survival way tougher by changing your basic attributes. Every little thing becomes a challenge, and even the simplest tasks feel dangerous.
Main Changes Half Health: You only get 5 hearts total. Every hit is a risk.
No Swimming: You sink in water. Rivers and oceans are deadly.
Fire Burns Longer: If you catch fire, it lasts 30 seconds. Lava is basically a death sentence.
Weak Attacks: Your fists only deal 0.2 damage. Fighting mobs is slow and painful.
No Jumping: The jump key makes you do a short dash instead (not really on purpose, but it works).
Tiny Jump Boost: With Jump Boost II, you can just barely hop onto a trapdoor. That’s it.
Short Reach: You can only hit or break things from 1.5 blocks away.
Slower Speed: You move a little slower than normal.
