📋 About This Mod
### SentryCore: Base Defense Defend. Upgrade. Survive. SentryCore is a simple tower defense plugin for Paper 1.21.x. Move beyond standard iron golems and generic traps—SentryCore allows you to engineer, deploy, and evolve sentries that protect your base with everything from standard projectiles to Warden-class sonic booms. ### Key Features + Physical Build Requirement: Sentries aren't just placed; they are constructed using a specific block structure involving Barrels and Obsidian frames. + Three Tactical Firing Modes: Switch between Amethyst (Standard), Prismarine (Laser), and Echo (Sonic Boom) modes to adapt to any threat. + Upgrade System: Spend Condensed Obsidian to level up 5 distinct stats across 40 tiers. + Emergency Protocol: A revolutionary safety net that heals the owner or triggers a Ghost Totem (no item required) if you take fatal damage near your core. + Smart Targeting: Full GUI-based whitelist/blacklist for every hostile mob in Minecraft. + True Portability: Pick up your Sentry at any time. All tiers, kills, and settings stay embedded in the item, allowing for easy relocation or trading. ### How to Build Your First Sentry Building a Sentry requires a multi-block structure to "ground" the Core's power: The Base: Place a Barrel (this stores your fuel). The Frame: Surround the Barrel with 8 Obsidian blocks on the same level. The Pedestal: Place 1 Obsidian block directly on top of the Barrel. The Core: Place your crafted Sentry Core (Conduit) on top of that Obsidian. **Tip**: Shift + Right-Click the Core to open the Control Panel! ## Firing Modes Your Sentry consumes fuel directly from the Barrel beneath it: + Amethyst (Standard): High-speed projectiles. Reliable and cheap. + Prismarine (Laser): A continuous tracking beam. Perfect for fast-moving targets. + r45Echo (Sonic Boom): Massive burst damage that bypasses armor. The ultimate defense. ### The "Guardian's Grace" Upgrade One of SentryCore's most powerful features is the Emergency Healing track. As you upgrade this stat, the Sentry monitors your health: Tiers 1-9: Grants Regeneration, Resistance, and Absorption buffs if your health drops too low. Tier 10 (The Life-Saver): If you suffer fatal damage, the Sentry triggers a Resurrection Protocol, granting you a Totem effect and invincibility for 5 seconds to get you back in the fight. ### Installation & Requirements Platform: Paper 1.21.x Java Version: Java 21 ### Contact: Discord (https://discord.com/users/1020708526932377660)
