vermin vigil block

A placeable vermin-spawning block. When set down, this block becomes the Spawner Block, an interactive living block that accepts a vermin capsule and keeps nearby vermin active.

It is a glass block with a metal ball in the center that glows, and it emits metal-sphere particles once a capsule has been placed inside. Spawn timing is set per vermin: a Leviathan capsule takes roughly ten times longer than a Bunnicorn, while a Baal capsule spawns very fast.

This can be generated easily through Dilution — combine a large amount of these with a small amount of something else, like nuts or fish corpses, to create a Vermin Oracle, then Dilute again to turn it back into this item.
