A horror, high-difficulty, and mystery modpack heavily inspired by RLCraft.
This modpack turns Minecraft into a hostile and dangerous world, where almost nowhere is truly safe. Flat biomes, deep caves, and even mountain bases present constant threats, from dark creatures to unexpected events.
Main Features:
- Extreme difficulty system with much more dangerous and aggressive mobs
- Realistic temperature, thirst, hunger, and sanity mechanics
- Heavy horror atmosphere with constant tension
- Possibility to tame several types of dragons (including the Ender Dragon under specific -conditions)
- Legendary items, dragon armors, powerful weapons, and magic systems
- Focus on exploration, preparation, and long-term survival
You spawn with a short grace period to prepare before environmental effects (such as temperature) begin to affect your character. This pack was made for players who think regular Hardcore is "too easy". Strongly recommended in Hardcore mode.
Multiplayer: Works perfectly with Essential or Vanilla LAN.
It's my first modpack published but i hope you enjoy it! :>
