    Description:

    The Emerald Sentinel Tower is a powerful automated 8x8x8 multiblock defense structure that, once built, is activated by right-clicking with the Defense Wand to register yourself as its owner; the tower will automatically detect and obliterate hostile mobs within a 32-block radius with a green particle beam and notify you via chat when threats are engaged. Sneak and right-click with the Defense Wand to toggle Defense Mode, which creates a visible red particle border and gives non-owner players a 10-second warning before instantly eliminating them, and right-clicking any block of the tower will show its current status. This update polishes the visuals: the tower now has a shiny emerald crystal glow and the Defense Wand uses a matching emerald-glowing texture that displays correctly in-hand and in inventories.

    Emerald Sentinel Tower

    Quickstart

    1. Craft the tower using the recipe below, which gives you the base block.
    2. Place the base block on the ground — the full 8×8×8 multiblock structure auto-assembles instantly, facing toward you.
    3. Craft or find the Emerald Defense Wand in the Functional or Combat creative tabs (or obtain it via /give).
    4. Right-click the wand while standing within 64 blocks of the tower to activate it and register yourself as owner. You'll see a confirmation message and hear a beacon sound.
    5. The tower immediately begins hunting hostile mobs within 32 blocks, firing a green particle beam and notifying you in chat.

    ⚠️ Tower state is not saved on server restart — you must re-activate with the wand after each restart.


    Overview

    The Emerald Sentinel Tower is an automated 8×8×8 multiblock defense structure with a shiny emerald crystal glow. Once activated, it acts as a fully autonomous guardian — eliminating hostile mobs, and optionally enforcing a no-trespasser zone for non-owner players. The Emerald Defense Wand is its control item, featuring a matching emerald enchantment glow in hand and in inventories.

    How To Use

    Placing the Tower

    Place the Emerald Sentinel Tower block anywhere on the ground. All 8×8×8 structure parts are placed automatically around it. The front of the structure faces the direction you're looking when you place it.

    Activating the Tower

    Hold the Emerald Defense Wand and right-click while within 64 blocks of the tower:

    • Registers you as the owner.
    • Activates automated mob elimination.
    • Chat confirms: "✓ Tower ACTIVATED – Hostiles will be eliminated!"

    Right-click again to deactivate the tower.

    Checking Tower Status

    Right-click any block of the tower structure to see its current status in chat.

    Toggling Defense Mode

    Sneak + Right-click with the Emerald Defense Wand to toggle Defense Mode:

    • A red particle border becomes visible around the tower.
    • Non-owner players entering the zone receive a 10-second warning.
    • If they do not leave within 10 seconds, they are instantly eliminated.
    • The owner is never affected by Defense Mode.

    Sneak + Right-click again to deactivate Defense Mode.

    Progression And Strategy

    • Early placement: Put the tower near your base entrance — its 32-block radius covers a wide perimeter and requires no upkeep once activated.
    • Defense Mode for PvP servers: Enable Defense Mode to protect your base from other players. The 10-second warning gives innocent passers-by a chance to retreat, while determined intruders are eliminated automatically.
    • Multiple towers: Place towers at strategic corners or chokepoints. Each wand interaction targets the nearest tower, so stand close to the one you want to configure.
    • After a server restart: Towers remain physically intact but lose their active state. Simply right-click with the wand to re-register ownership and reactivate — this takes only a second.
    • Visual identification: The glowing emerald crystal appearance and the wand's enchantment shimmer make both items easy to spot in your inventory and in the world.
