Setting Up a Hollow Spawner and Reading Its Drops
Placing the Hollow Spawner
Hollow Spawner is a placeable block. Set it down where you want mobs to appear — typically inside a controlled room built from Shaded Stone Bricks, Shaded Stone Brick Slab, Shaded Stone Brick Stairs, and Shaded Stone Brick Wall. Surround it with a Grave Soil floor and light the area with a Blight O'Lantern so you can see what spawns.
What It Produces
The Hollow Spawner is tied to the mod's hostile mobs: Revenant, Haunter, Demon, Wandering Knight, and Wandering Knight Leader. Each has a corresponding Spawn Egg — Revenant Spawn Egg, Haunter Spawn Egg, Demon Spawn Egg, Wandering Knight Spawn Egg, and Wandering Knight Leader Spawn Egg — which you can use to place a specific mob directly instead of waiting for the spawner.
Collecting Drops
Kill the spawned mobs to gather Monster Ashes, Ectoplasm, Embers, Rotting Arm, Fractured Plating, Cursed Cloth, and Spawner Shard. These feed into the mod's other recipes, including the Deathbringer and Wandering Knight armor lines and the Grave Scythe. Build a kill corridor with Shaded Stone Brick Walls so mobs funnel toward you, and keep a Fang Sword or Grave Scythe ready.
