☠ Curse Keeper

A Minecraft Java Datapack — Unique Curse System

Compatible with Minecraft Java 26.x (pack format 88)

What is Curse Keeper?

Curse Keeper is a datapack that puts every player under a personal curse from the moment they join the world. Each curse comes with its own unique cleanse tribute — a specific challenge that must be completed to lift it. Once lifted, a cooldown of 6 in-game days passes before the next tier of curse is assigned. Progress through all three tiers and the player is free of curses forever.

The system is entirely per-player — everyone is on their own curse journey, independent of others. Some will push through every tier quickly, others might choose to live with their curse indefinitely. There's no timer forcing your hand.

⚠️ This datapack is still in active development. More curses will be added in future updates. Currently 16 curses are implemented.

How It Works

The Three Tiers

Every player progresses through three tiers of curses, in order:

1. Tier 1 — The player starts cursed. Complete the cleanse tribute to lift it.
2. Tier 2 — After a cooldown of 6 in-game days, a new curse is assigned. Complete its cleanse tribute to lift it.
3. Tier 3 — After another 6-day cooldown, the final curse is assigned. Lift it and the player is permanently free of curses.

The 6-day cooldown only begins after the previous curse has been cleansed — there is no time limit to complete a cleanse tribute. A player can live with their curse as long as they want, or work towards removing it on their own terms.

Cleanse Tributes

Each curse has its own unique cleanse tribute — the specific challenge that must be completed to lift it. Examples include:

• Kill a certain number of a specific mob (e.g. kill 150 Skeletons)
• Earn a specific in-game advancement
• Consume a specific item a set number of times
• Reach a certain milestone while cursed

The tribute varies per curse, so every tier may require a completely different kind of challenge.

Curse Effects

Curses affect players in different ways depending on which curse they receive. Current effect types include:

• Reduced max hearts — permanently removes a set number of hearts while cursed
• Dimension damage — the player takes damage when entering or staying in certain dimensions
• End access blocked — the player is prevented from entering the End
• Reduced movement speed — the player moves significantly slower
• XP drain — experience levels are slowly siphoned away over time
• Mob aggro — certain mobs within range aggro onto the player automatically
• Sunlight burn — standing exposed under the sun in the Overworld sets the player on fire
• Moonlight burn — standing exposed under the night sky sets the player on fire
• Water damage — being submerged in water deals constant damage
• Villager sickness — proximity to villagers applies Poison and Nausea
• Nature's toll — breaking grass blocks periodically applies Slowness
• Sleep penalty — each time the player sleeps, they lose 1 max heart permanently
• Death penalty — each death permanently removes 1 max heart

Admin Setup

To grant a player access to the admin panel, run the following command in-game as an operator: /tag <player> add ck.admin

This must be done for each admin after every season reset. To revoke access: /tag <player> remove ck.admin

Without this tag, players will not be able to open the admin panel via /trigger ck.admin.
