DatapacksJava
HCIM (Hardcore Ironman)
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Implementation of Minecraft Hardcore Ironman from OldSchool RuneScape.
Features
- 2 new advancements trees
- 1 tree that can only be completed before the player dies, and another for after the player dies.
- Death isn't the end
- Once you die, you will be able to respawn. The only caveat is that you can no longer complete the "before death" advancement tree, but you do get an "after death" advancement tree.
- Collection log
- Apart of the "before death" advancement tree. This gives the player a long term goal.
Install this datapack if you...
- Still want the risk of playing hardcore without risking your time
- Like the idea of a collection log as a sort of secondary goal
WARNING!: This datapack is not finished (and it shows!!!), but I do plan on adding more advancements/features.
