Mischievous Skull
by cprodhomme
Mischievous Skull adds a skull block that grants a random status effect to the player who destroys it, with durations set by a data file.
What it does
Once a skull is destroyed, the player gains a single randomly chosen effect at level one, drawn from a list that includes Strength, Speed or Haste. Effects can run for a fixed number of game ticks, where 20 ticks make one second, or last indefinitely when the duration is omitted or set to 0. The effect list, the durations and the choice of effects are read from a JSON file in the data folder, so a world can be tuned without changing the jar.
The mod ships a default effects file inside its jar. A datapack or resource pack using the same path overrides it, and a dedicated server can reload the data after a change. If the file is missing or invalid, the mod switches to a built-in set of nine effects.
Mischievous Skull is built for Fabric and runs on client and server, so the server and every player need it. Files cover 1.20.6, 1.21.1 and 1.21.11, and the latest build targets 1.21.11. The code is not open source and is published under All rights reserved, although the source code is public.
Key features
Random skull effects
A destroyed skull gives the player one random level-one effect, which makes each skull a small surprise.
Configurable durations
Each effect has a duration in game ticks, and omitting the field or setting it to 0 gives an infinite duration.
Data-driven effect list
The effect list lives in a JSON file that datapacks and resource packs can override, including modded effects by identifier.
Adventure map placement
Skulls can be placed at key locations in adventure maps, adding unpredictability to quests and challenges.
