only's invis hardcore
Everything is invis, everything wants you dead.
You can't see the mobs. They can see you.
Features
- Invisible mobs. Every living mob is invisible, with no potion particles. Armor and held items can still show.
- Every mob attacks. Zombies, skeletons and the rest hunt you like normal. Cows, pigs, rabbits, villagers and every other mob that normally ignores you now chase you and hit you when they reach you. Fish and squid stay in the water.
- Double health and double damage. All mobs have twice the health and hit twice as hard in melee, and they move faster and notice you from further away.
- Nearby entity counter. An actionbar line shows how many mobs are within 32 blocks, like "Nearby Entities: 7". Nothing else shows where they are. No glowing, markers or locator bar.
- Kill effect. Killing a mob plays a short particle burst.
- Join screen. When you join, a title and a chat message tell you what you're getting into.
- Built-in anticheat. The pack keeps the world on Hard and sets anyone in creative or adventure back to survival within a fraction of a second, even with cheats on. Spectator still works for dead Hardcore players.
- No resource pack needed.
How to install

Notes
- Arrows, explosions and fireballs aren't doubled, only melee damage.
- A datapack can't turn an existing world into Hardcore, so create the world as Hardcore.
