Froggo's Armadillo Infesting XP Farm

Ensure there is no deepslate, stone, cobblestone, stone bricks, mossy stone bricks, cracked stone bricks, or chiseled stone bricks where the silverfish spawn: otherwise, the silverfish will enter the blocks.

Fill the dispenser with splash potions of infestation.

Place 12 armadillos in the chamber.

Ensure the zombie does not die: if it does, the armadillos will die as well.
