Small Mob Repeller is the first tier of the Ala Industrial guard-field line for Minecraft 26.2: while the block is powered, hostile mobs flee a cube with an 8-block radius (17×17×17) and cannot approach your base. The field sweeps the zone twice a second: zombies, skeletons, creepers and spiders turn and run past the boundary, phantoms, ghasts and slimes are pushed outside, and an angered enderman teleports away. Passive animals, villagers and players are untouched, calm neutral mobs are left alone until provoked, and the single exception is the shulker, which stays anchored to its block. Piglins and hoglins fear the block natively, the way they fear soul torches, and while the field is running the emitter on top glows teal at light level 14.

The field of the Small Mob Repeller is an upkeep cost, not a per-mob fee: a constant 8 EU/t while enabled, input of up to 32 EU/t (LV) through any face, and a 2,000 EU internal buffer that rides out short outages. A redstone signal switches the field off and stops the drain, so a lever doubles as a power switch. Craft Small Mob Repeller at a crafting table from four silver plates, a soul lantern, two copper coils, an advanced machine casing and an advanced circuit, then insert a Soul Vessel filled with 80 souls — the block grows into the Medium Mob Repeller with a 16-block radius and keeps its stored energy. Torches inside the zone are still needed: the field drives mobs out but does not stop them from spawning.
