Cataclysm Era

This is a mod focused on hardcore post-apocalyptic survival. Its core feature lies in adjusting zombie stats based on in-game time, without any modifications to zombie AI. It is recommended to play alongside other zombie-enhancing mods.
Key Features:

• Displays the current in-game day count every morning.
• Zombies are no longer vulnerable to sunlight (only immune to sunburn, not fire damage).
• Zombies receive a power-up every 10 in-game days.
• Every 10th night becomes a special night event.
• Zombies have a chance to spawn with invisibility.
• In the mid-to-late game, zombies may spawn holding Totems of Undying.
• In the late game, zombies have a chance to spawn fully equipped with netherite armor.
• Zombies replace some of the vanilla game's monsters.
• Zombies drop a wider variety of items.

This mod offers high flexibility, with most adjustable values accessible in the configuration file.

Compatibility Note:
If you have the Enhanced Celestials mod installed, every 10th night will be set as a Super Moon.
