ProMB v2.0 - The Ultimate Modular Boss Engine
Create, manage, and schedule advanced custom bosses entirely in-game with zero lag.
Detailed Product OverviewProMB (ProMobBoss) v2.0 is a next-generation PvE and Boss management plugin designed for Spigot and PaperMC servers. We have completely rewritten the traditional boss plugin concept by abandoning heavy, lag-inducing YAML configurations and global tick timers. Instead, ProMB utilizes a "Library-First" architecture, offering server owners a 100% in-game GUI-driven experience combined with a highly optimized, asynchronous Smart Grid spawning system.
Whether you want to create simple vanilla bosses with custom armor, or complex raid bosses using our direct MythicMobs integration, ProMB handles it all. Every aspect of your boss—from its health and damage to its exact spawn schedule and custom skill triggers—can be configured directly through our intuitive graphical user interface. This ensures maximum server performance while providing an unmatched level of customization for RPG, Survival, and Factions servers.
Comprehensive Feature Breakdown1. Complete In-Game GUI Editor
Say goodbye to syntax errors and server reloads. ProMB features a massive, paginated 54-slot GUI dashboard. You can create a new boss using a command, open the editor, and instantly modify its Display Name, Max Health, and Attack Damage. Want to equip your vanilla boss? Simply click your own armor and weapons directly into the boss's equipment slots via the GUI.
The main Boss Editor Hub where every setting is just a click away.
2. Data-Driven Custom Skill System
Bosses are no longer just damage sponges. ProMB introduces a highly customizable skill system. You can create custom abilities via YAML files using actions like Lightning, Damage, Knockback/Push, Potions, and Commands. Once created, you use the GUI to assign these skills to bosses with specific triggers (e.g., ON_HIT, ON_DEATH, TIMER_10S, HEALTH_BELOW_50) and target types (e.g., NEARBY_PLAYERS, AGGRO_TARGET).
Easily attach custom skills and set their triggers and cooldowns in-game.
3. Real-Time Advanced Scheduling
Standard interval timers are a thing of the past. If you want a boss to spawn specifically on "FRIDAY at 20:00:00" or "DAILY at 14:30:00", our Schedule Manager handles it. The system calculates the exact millisecond until the next spawn, ensuring your server events happen precisely on time, even after server restarts.
Set exact days and times for your bosses to automatically spawn.
4. Vanilla & MythicMobs Dual Engine
ProMB supports two distinct entity engines. You can browse and select from all available Vanilla Minecraft entities through a paginated GUI menu. If you prefer advanced mob creation, ProMB seamlessly hooks into MythicMobs—just input the internal MythicMob ID, and ProMB will handle the spawning, leashing, and reward distribution.
Select any vanilla entity from our paginated spawn-egg GUI.
5. Vector-Based Region Leashing
Keep your boss fights contained within your custom arenas without relying on third-party region plugins like WorldGuard. ProMB includes a custom Region Wand. Select two points to create a 3D bounding box. If a boss is knocked out or tries to walk out of this arena, our physics engine applies a smooth vector velocity to push them back to the center.
6. Dynamic Reward & Loot Distribution
Distribute loot fairly. You can configure rewards to drop directly onto the ground, or be placed straight into players' inventories. Choose distribution modes such as 'Last Hit', 'Top Damage', or 'Random Nearby Player'. Every single reward supports custom RNG drop chances (e.g., a 2.5% chance to drop a legendary sword).
Engage in epic boss battles with custom skills and guaranteed server performance.

Database & Under-the-Hood OptimizationProMB is built for scale. It uses HikariCP for lightning-fast, asynchronous database connection pooling. You can choose between a local SQLite file or a remote MySQL database to track boss kills, fight durations, and killer UUIDs. Furthermore, our asynchronous Smart Grid Spawner ensures that entity scanning for random spawns never runs on the main server thread, guaranteeing flawless TPS.
