Kimetsu Spawner

The Kimetsu spawner is a reusable block for configured encounters. It can spawn the mod's Slayer NPCs and demon variants, including Zenitsu and Thunder Slayers. It is separate from natural demon spawning.

Selecting an Entity

Find the block in the creative inventory. Right-click it without a spawn egg to open its editor; this requires operator permission level 2. Choose an entity and save the settings. An unconfigured spawner does not spawn anything.

You can also use a supported spawn egg on the block to set its entity. Slayer eggs preserve the named NPC profile, and demon eggs select their variant. Using an egg consumes one egg.

For the available eggs, see Hashira and Slayers.

Settings

Each block stores its own settings:

Setting	Default	Effect
Minimum delay	200 ticks / 10 seconds	Lower end of the spawn delay.
Maximum delay	800 ticks / 40 seconds	Upper end of the spawn delay.
Spawn count	4	Spawn attempts per cycle; successful spawns still depend on space and limits.
Maximum nearby entities	6	Nearby population limit.
Tracking range	32 blocks	Radius used to count nearby matching entities.
Required player range	16 blocks	A player must be close enough for the spawner to run.
Spawn range	4 blocks	Area around the block in which spawn positions are attempted.
Respect spawn rules	Off	When enabled, checks the selected entity's normal spawn rules.
Persistent mobs	On	Marks spawned mobs as persistent so ordinary distance despawning does not remove them.

Reusing a Setup

Picking or breaking the block produces a configured copy that preserves its settings. Place it elsewhere to reuse the encounter setup.

Disabling natural demon spawning does not disable Kimetsu spawners, spawn eggs, or commands. Adjust those encounters independently of the natural-spawn settings.
