Very Hard Difficulty

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.
