    Vanilla mobs are slow, easy to kill, and sometimes boring.

    This is a large datapack made for one purpose:

    Making Minecraft hard while staying RP


    ---

    >High difficulty while keeping a regular minecraft, vanilla feel

    No janky stuff.
    No new mobs.
    No custom textures.

    No overpowered senseless mobs.
    No uniform zombies all wearing protection 4 armor for some reason.

    How can you immerse yourself in the world when mobs are wearing stuff that doesn't make sense?
    When mobs have effects that make no sense for what they are?
    You can't

    That's the philosophy of Doom Hardcore,
    the go-to difficulty datapack with a realistic, vanilla feel.

    The three main features adding difficulty in DH are the following:


    >1. Everything is harder to kill
    In vanilla, you'll find that an iron sword is enough to kill most mobs in under 1.5 seconds.
    With two crits and a normal hit, you already did over 24 damage, when most mobs have around 20 health points.

    In DH, you'll see that this is not possible until you obtain fully enchanted netherite weapons.


    >2. Melee mob charge and knockback resistance
    In vanilla, most mobs, including melee mobs, are very slow.
    Even by walking you can outrun them.

    And even worse is that you can knock them back dozens of blocks away within seconds if you know about sprint knockback attacks.
    Result: you have complete control over their positioning,
    and being cornered is not problematic since you can knock mobs away easily.


    In DH, not only are most melee mobs very fast, they also have charge knockback resistance,
    much like how players do when sprinting in PVP.

    So you have to be really careful of your positioning, not to be cornered,
    otherwise you will not be able to knock them away and you will be butchered.



    >3. Mobs follow you further
    In vanilla, most mobs only see you from 16 blocks away, which for a player is nothing.
    You can run for two seconds and you will lose their aggro.
    Zombies follow you up to around 34 blocks away, but they're so slow it doesn't matter.


    In DH, most mobs see you from twice as far away.
    Not only is it more realistic, it also highly increases the risks of being out in the open at night or in a large cave.
    Mobs want you dead, they don't just give up after a few seconds.

    Those are the major difficulty makers.
    But DH also gives special attributes and abilities to most mobs.

    For instance, skeletons can wear armor and use melee weapons.
    They can also sometimes spawn as 3 block tall giants.

    Creepers come with unpredictable fuse times and explosion strength.
    Some can lay a black smoke screen unpon exploding, which blinds players.

    Zombies call reinforcement when hit
    (More than vanilla)

    Husks are bigger than vanilla and see you from very, very far away


    Phantoms come in varying sizes.

    Evokers summon way more fangs and can stop your projectiles.

    Boggeds shoot arrows with nausea and longer poison.


    Ghasts take four fireballs to die.

    Blaze fireballs create rows of fire on the ground.

    Wither skeletons can sometimes be archers and will shoot explosive arrows.

    Magma cubes adapt their jump distance depending on your position, so they always land on you.

    Wardens swim fast :D

    The Wither will take you in the sky with it at the second phase of the fight.
    It's also very resistant at the second phase.
    Bring a smite sword.


    Angry endermen are very angry.

    The Ender Dragon's breath is absolutely deadly.

    And so on...

    There are many other changes like this which you will discover through playing.
    I'm confident that you will like it.

    Have fun rediscovering the game with DH!

    This datapack is compatible with multiplayer and fairly optimized.
    With some users we noticed that 20 players was about the limit before the tps would go down.
    So, for a small server with friends this datapack is definitely usable.

    Pack also come with options for:
    >Experience based regeneration (instead of food)
    >Cooler enchanted golden apples
    >Disabling player night skipping
    >Naturally spawning withers in soul sand valleys


    See the game start message for editing settings, or do /function settings:show
    (you need command permission to do so)



    This datapack only works for 1.21.5
    Mojang changes datapack format every version now and I can barely keep up.
    So from now on i'll only support the latest version :<

    Current compatible version:
    1.21.5
    1.21.5
    1.21.5
    1.21.5

    But here is the previous 1.21.4 version (still very good uwu):

    Update #14.3 : by deltamachine 05/28/2025 3:44:41 pmMay 28th

    ### 14.3

    The 1.21.5 update.
    Mojang keeps up its new habit of breaking every single datapack in existence at every sub-version, but alas I have finally fixed everything that broke.
    Command formats, particularly related to armor and weapons, were changed. I think /tellraw format was changed too and I had to fix all my options menu text.
    Oh well I forgot to write down everything that I fixed, however here are the visible changes for this update:
    >Added option to turn off increased experience
    >Skeleton horse traps just got spicier
    >Wither skeletons can now spawn with golden armor
    >Ender Dragon breath gives you nausea now too xD
    /!\
    The datapack is now only working on 1.21.5
    /!\
    I'll leave the 1.21.4 version on a catbox link for a while

    Also, how to turn off the moody effect on the screen when not full health. It would be stuck forever if we dont regenerate. Since we were playing in no regen mode, this feature is pretty annoying.

    I don't think it's my datapack, I don't add a vignette or anything when not full health so maybe it's another mod you have installed?

    How to disable increased XP and drop rate? Me and my friends found it useless to make a farm with this function activated. We want to disable it but don't know how.
