Beacon with negative effects

A beacon variant that applies negative effects instead of positive ones, designed to protect players and their bases from being attacked or griefed. The beacon does not affect the player who created it or trusted players, but weakens hostile mobs and enemy players within its range using effects such as Mining Fatigue, Slowness, or Weakness. With familiar beacon-style controls and optional redstone activation, this defensive beacon feels natural to Minecraft's gameplay while giving players a powerful, late-game tool for area protection.
