The Hardcore Alchemy modpack is a hardcore/magic/survival modpack.

🦋 What is Hardcore Alchemy?

Hardcore as in Hardcore Mode (but you keep your world).

In Hardcore Alchemy, you live as a shapeshifting mage in an unforgiving world. You can use your morphing ability to avoid combat, but only for a limited time. When you die, you respawn elsewhere and are unlikely to find your old base again. But over time, you may accumulate resources or magic research which stay with you.

Become a powerful mage or get stuck as a chicken for the rest of your life. When you die, the negative effects of the magic you have acquired are erased, allowing you to forge a new path. A curated selection of magic mods are enhanced with custom-coded mechanics, adding additional tradeoffs.

Thoughtful survival.

You are weak, and have additional survival needs like nutrition and thirst. Stone is harder, food will decay, and you will have reduced starting health that can be upgraded through various challenges... or sacrificed.

A curated selection of survival and mob mods have been thoughtfully configured and modified to strike a balance of fairness and difficulty. Some survival mechanics have been custom-coded with this modpack in mind.

Play at your own pace.

Choose when you are ready to venture from the safety of your base. Mobs will not relentlessly dig through your base to get to you. You are not on a timer. And you will rarely be trapped in your base with nothing to do.

A craftable in-game guidebook, "The Traveling Alchemist," gives you guidance on how to survive and progress. Once you have the tools necessary for your survival, what you do next is up to you.

The main guide to the pack is called, "The Traveling Alchemist;" it is available here in the wiki, and is also craftable in-game using early game materials. Crafting a shovel is strongly recommended.

Announcements

  • (2026-07-04) Released Hardcore Alchemy modpack version 0.8.7, fixing the same morph-related bugs in the mod suite.
  • (2026-07-04) Released Hardcore Alchemy mod suite version 0.8.6, fixing a sadly longstanding bug where permanently morphed players were often missing dietary restrictions and related settings. This version also fixes the Fallen Mount from Ender Zoo sometimes attacking morphed players.
  • (2026-06-28) Released Hardcore Alchemy modpack version 0.8.5, which adds new heart upgrades with tradeoffs, and fixes Cooking for Blockheads not preserving dietary restrictions.
  • (2026-01-25) I have had no luck so far reproducing my own bug. If you encounter this and are able to obtain your logs for the given session before you restart the game, it could be helpful (particularly instances/Hardcore Alchemy [latest version]/minecraft/minetweaker.log and instances/Hardcore Alchemy [latest version]/minecraft/logs/fml-client-latest.log)
  • (2026-01-19) It has come to my attention that, in the latest update, recipes can sometimes break, i.e. you look up the recipe in JEI but it doesn't work when you put it in the crafting table. Closing and re-opening the game seemed to fix this, so that's a workaround you can try for now. I think this is caused by re-loading the world and only applies to custom CraftTweaker recipes, like the Elevator recipe.
  • (2025-02-08) Released Hardcore Alchemy modpack version 0.8.4, which adds missing potion recipes (finally) and various magic integrations.
  • (2024-05-26) Released Hardcore Alchemy mod suite version 0.8.3, which includes a fix for Blood Magic rituals stopping on owner relog.
  • (2023-12-22) Security hotfix 0.8.2 release. Changelog here.
