About this project

What does Very Hard Difficulty add?

Very Hard Difficulty

Adds a vanilla-style "Very Hard" difficulty to the world creation menu — no commands needed. It slots right next to Peaceful / Easy / Normal / Hard, exactly like an official Mojang difficulty would.

Pick Very Hard (or Hard) in the difficulty selector and the world gets harder instantly. Every change reverts the moment you switch back — nothing is permanently baked into your world.

Features

Survival is unforgiving

  • Shields absorb 80% of incoming damage instead of 100% — 20% always leaks through.
  • Heavy hits break your guard — a strong attack puts your shield on a 5-second cooldown.
  • Hunger drains 1.5× faster.
  • Health regeneration costs more on your hunger bar.
  • Armor wears out 20% faster.

Mobs fight smarter

  • Zombie hordes — zombies call nearby allies when they spot you.
  • Zombies climb — they can climb ladders and vines to reach you.
  • Skeletons aim predictively — they lead their shots.
  • Tipped arrows — some skeletons fire tipped arrows that inflict effects.
  • Creeper shockwave — a nearby creeper blast leaves you Nauseous and Blind for 4 seconds.
  • Endermen flank you — they teleport behind you more aggressively.
  • Phantoms are relentless — they can knock the shield out of your hands, and they spawn sooner (after 2 days without sleep instead of 3).

Harsher world

  • Fall damage debuff — hard landings apply Slowness II for 10 seconds.
    • Freezing biomes hurt more — Slowness and steady freeze damage, unless you're near a heat source or wearing full leather armor.
    • The Nether is hostile — continuous Weakness in the Nether, unless you're under Resistance.

FAQ

Is this like other hardcore mods?
No — it's built to feel like an official Mojang difficulty. No new blocks or items.

Will it break my world?
No. Changes apply only while active and revert instantly.

Can I turn features off?
Yes — every feature has its own toggle in config/very_hard_config.json.

Why doesn't Very Hard just make mobs hit harder than Hard?
Because it is Hard underneath — vanilla damage, hunger and raid rules all run at Hard level, and the mod layers its own changes on top. That keeps it feeling like a real difficulty instead of a damage multiplier.
