Aetheric Nullifier Beacon
By yurian
The Aetheric Nullifier Beacon is a placeable artifact that projects a 360-block spherical field preventing natural spawning of hostile, passive, ambient, and water mobs while periodically purging hostile mobs plus nearby cows, chickens, pigs, sheep, horses, and bats with a visible shockwave; tamed or name-tagged creatures, villagers, iron golems, snow golems, Wandering Traders, and Villager Guards are exempt. It only activates its suppression field, shockwave purging, light emission, and dome rendering while receiving redstone power; place the beacon to register it (it persists across restarts and chunk reloads), right-click to toggle a synced light-blue dome overlay and view status text reporting whether the beacon is active or waiting for redstone power, and in Survival the block can only be broken with a diamond pickaxe and is immune to TNT, the Wither, and the Ender Dragon.
