Description
This mod adds a deployable base-defense system: place a Diamond Base Beacon (you receive a starter beacon or can craft one) to designate your base and spawn up to four Female Sniper Sentinels that guard it around the clock. Sentinels wear custom diamond-themed tactical armor, have 4500 HP, carry a .50 Cal Sniper Rifle that deals massive sniper damage to hostile mobs, and are leashed to the beacon so they teleport back if they stray. Missing guards are automatically replenished every two in-game days, and anchors persist across reloads so you can focus on building while your squad holds the perimeter.

Diamond Base Sentinel
Quickstart
- Join the world — on your very first spawn you automatically receive one Diamond Base Beacon in your inventory.
- Go to the spot you want to defend, then use (right-click / tap) the Diamond Base Beacon anywhere.
- A squad of four Female Sniper Sentinels immediately spawns around that spot and begins guarding it — you're done!
- If you ever need a replacement beacon, craft one at a crafting table (see Crafting And Obtaining).
Overview
Diamond Base Sentinel gives every player a personal automated defense squad. Place a Diamond Base Beacon to anchor your base, and four elite Female Sniper Sentinels will patrol the area, gun down hostile mobs within 48 blocks, and teleport back to the beacon if they wander too far. The system is persistent — your squad survives world reloads and automatically replenishes any fallen guards roughly every two in-game days.

How To Use
Setting Your Base
Hold the Diamond Base Beacon and use it (right-click on PC, tap on mobile, LT/L2 on console). The beacon sets an invisible anchor at your current location and immediately spawns four sentinels arranged in a ring around you. A chat message confirms the anchor is set.
- Each player can have one active base at a time. Using the beacon again moves the anchor to the new location.
- The anchor persists across world reloads — your squad will be right where you left them after logging back in.
Sentinel Behavior
- Sentinels attack any hostile mob within 48 blocks of the beacon.
- Each shot deals 300 damage, shown with a critical-hit particle effect.
- If a sentinel strays beyond 36 blocks from the beacon, it teleports back automatically.
- Sentinels do not attack other sentinels or players.
Auto-Replenishment
If any sentinel dies, missing squad members are automatically respawned approximately every two in-game days. You never need to manually replace guards.
Loot
When a Female Sniper Sentinel is killed it drops 1–3 diamonds. It does not drop its armor or rifle.

Abilities And Mechanics
| Stat | Value |
|---|---|
| Health | 4,500 HP |
| Attack damage | 300 per hit |
| Detection / attack range | 48 blocks |
| Leash radius (teleport back) | 36 blocks |
| Respawn check interval | ~2 in-game days |
| Squad size per player | 4 sentinels |
- Ranged combat: Sentinels engage from range, prioritising the nearest hostile mob in their detection radius.
- Amphibious navigation: Sentinels can path through water without drowning.
- No experience reward: Killing a sentinel yields no XP.
- Named guards: Each sentinel is named after its owner (e.g. Steve's Female .50 Cal Sentinel) so you can tell squads apart on multiplayer servers.
- Enchantable armor: All four pieces of sentinel armor can be enchanted by the player if obtained.
Progression And Strategy
- Early game: Use the free starter beacon as soon as you have a base location. The sentinels will handle surface hostiles so you can mine and build safely.
- Resource investment: Crafting a replacement beacon costs 3 diamonds + redstone + obsidian. Prioritise finding diamonds before you need a second beacon.
- Relocating: Simply use the beacon at your new location. The old squad is abandoned and a fresh squad spawns instantly at the new anchor.
- Multiplayer: Each player gets their own squad of four. Sentinel names include the owner's name, making it easy to identify whose guards are whose.
- Defense gaps: Sentinels cover a 48-block radius, but mobs approaching from below (caves) may not always be targeted. Supplement with walls or lighting underground.
- Keeping your squad intact: Avoid building in areas where creeper explosions could reach your sentinels — with 4,500 HP they are very tough, but sustained siege events can wear them down before the two-day respawn window.
