Cursed Spawners

by Provismet

Cursed Spawners turns the spawner blocks of the game into hazards that knock players back, heal and speed up nearby mobs, and sometimes turn into mimics when broken.

What it does

The mod changes how spawners behave. Each spawner can randomly select up to seven actions that fire on a periodic timer or in response to events, such as knocking away nearby players, healing hostile mobs, granting them movement speed, summoning vexes or silverfish, or applying blindness and poison. A broken spawner can prevent its own breaking, be consumed in a way that acts like an extra life, or trigger a mimic that keeps spawning other mobs from the original spawner.

Three major features are controlled through gamerules and NBT data, so server owners can tune how dangerous spawners are. Mining speed for spawners is also modified. Builders and datapack makers can use the NBT settings to produce dungeons that rely on these behaviours. The mod requires Fabric API and is published for Fabric and Quilt, covering 12 release versions across 1.21.1 – 1.21.11. It runs on client and server, so both sides need it. The code is not open source; it is under a custom license.

Key features

  1. Periodic and reactive actions

    Spawners pick from a pool of effects that fire on a timer or when a player interacts with them.

  2. Spawner mimics

    A broken spawner may become a heavily armoured mimic that keeps producing mobs from the original spawner.

  3. Gamerule and NBT control

    Effect chance, radius, interval and efficacy are set through gamerules and NBT data on each spawner.

  4. Shrinking floor particles

    Three indicated particle effects mark the area where a spawner's actions reach.

Questions

Does Cursed Spawners need Fabric API?

Yes. Fabric API is a required dependency, so it must be installed alongside Cursed Spawners on Fabric or Quilt.

Do players need Cursed Spawners on their client?

Yes. The server and every player need the mod installed.

Can server owners change how strong the spawners are?

The three major features are controlled through gamerules and NBT data, so the effect chance, radius and interval can be adjusted.
