Heat And Climate Mod Wiki & Guide
The definitive guide to the Heat And Climate mod, a comprehensive overhaul of Minecraft's environmental mechanics, agriculture, metallurgy, and magic systems across versions 1.12.2 and 1.19.2.
Overview
Heat And Climate (HaC) is a massive overhaul mod that introduces a sophisticated environmental system to Minecraft. Unlike traditional survival mods that focus purely on difficulty, HaC focuses on a "climate puzzle" gameplay style where players must manipulate temperature, humidity, and airflow to process materials, grow crops, and survive.
The mod replaces standard crafting for many items with Climate Smelting, where blocks and entities transform naturally when placed in the correct environment. It also features a deep metallurgical system, a 5-color magic system inspired by classic fantasy archetypes, and a unique agricultural system involving wild crops and mutations.
