BuffMobs

Transform your Minecraft experience with progressive, customizable mob scaling that keeps the challenge fresh!
📋 Overview
BuffMobs is a comprehensive mod that intelligently buffs hostile and neutral mobs to provide a more challenging and engaging survival experience. Whether you want tougher early-game encounters or exponentially scaling late-game difficulty, BuffMobs has you covered with its flexible configuration system.
✨ Key Features
🏹 Smart Ranged Combat System
- Ranged mobs (Skeletons, Pillagers, etc.) dynamically switch to melee weapons when players get too close
- Automatic weapon generation with enchantments based on difficulty and dimension
- Weapon tier progression from stone to netherite over in-game days
- Configurable trigger distance and behavior mode (MELEE, KITE, or RANDOM per mob)
🌍 Dimension-Specific Scaling
- Configure unique multipliers for different dimensions
- Perfect for modded dimensions - make the Nether truly hellish!
- Independent scaling for health, damage, speed, armor, and more
- Up to 5 configurable dimension slots, plus optional fixed max health overrides per dimension
📅 Progressive Day Scaling
- Mobs get stronger as your world ages
- Configurable intervals (default: every 7 days)
- Optional chat notifications to track scaling progression
- Maximum scaling caps prevent infinite difficulty spikes
⚔️ Comprehensive Attribute Buffing
- Health Multiplier: Tankier mobs that survive longer
- Damage Multiplier: Hits that actually hurt
- Attack Speed: Faster, more aggressive combat
- Movement Speed: No more slow zombie walks
- Armor & Toughness: Damage reduction for elite encounters
🧪 Potion Effect System
- Apply Strength, Speed, Resistance, and Regeneration to mobs
- Infinite duration effects that refresh automatically
- Visual effect control for performance optimization
- Smart undead detection (no regeneration for zombies/skeletons)
👑 Elite Mobs
- Rare elite variants with bonus health and damage multipliers
- Fully customizable names: roguelike generated prefixes/suffixes (translatable) or translatable title prefixes
- Custom or random name colors, per-mob particle effects, and nearby player notifications
- Bonus XP and extra loot rolls on death, stacking on top of Loot & XP Scaling
🎭 Elemental Traits
- Each mob has a chance to roll one of six traits: FLAME, FROST, TOXIC, VOLTAIC, VAMPIRIC, or ARMORED
- On-hit effects: ignite, slow, poison, chain lightning, lifesteal, or permanent armor bonuses
- Passive immunities (fire, freeze, lightning, poison, wither) and per-trait particle visuals
- Fully weighted random selection with configurable chances and per-trait tuning
💀 Special Abilities
- Per-mob abilities assigned via ID mapping (
modid:mob_id:ability_id) - DEATHRATTLE: explodes, leaves a poison cloud, or summons minions on death (or random per death)
- LASTSTAND: triggers a Resistance buff once per life when HP drops below a threshold
- TELEPORT: blinks behind the attacker when damaged (safe destination checks included)
- SUMMON: periodically spawns minions while in combat, with alive-count caps
🧪 Combat Draft
- Hostile/neutral mobs drink a regeneration potion when their health gets low
- Undead variants instead receive Absorption and instant healing
- Configurable health threshold, cooldown, regen level, duration, and max uses per life
- Whitelist/blacklist filtering for full pack control
🌙 Blood Moon
- Periodic night event that boosts all mob scaling with an extra multiplier
- Optional glowing mobs and approximate spawn duplication during the event
- Doubles XP and extra loot rolls when combined with Loot & XP Scaling
- Global chat notifications and per-world cycle tracking, fully logical (never changes world time)
🧠 Adaptive Difficulty
- Difficulty adjusts dynamically based on player performance
- Player deaths increase the multiplier; buffed mob kills reduce it
- Configurable step sizes, reduction rates, and maximum bonus cap
- Layered on top of day scaling and Blood Moon multipliers
🛡️ Mob Armor
- Generated armor sets with tier progression (leather → gold → iron → diamond → netherite)
- Full-set or random-pieces mode, per-slot chances, and mixed-tier rolls
- Full enchantment support (protection, thorns, respiration, depth strider, frost walker, etc.) with unlock days and max levels
- Optional curse application (Binding, Vanishing) with configurable chance and unlock day
🎲 Mob Presets
- Assign stat presets to specific mobs via
modid:mob_id:preset_namemappings - Five configurable preset slots with per-preset health, damage, speed, attack speed, armor, and toughness
- Optional dimension scaling override so preset mobs ignore dimension multipliers
👥 Group Behavior
- Passive Mob Aggression: makes passive mobs fight back (OFF, NEUTRAL, or HOSTILE) with configurable damage scaling
- Pack Aggression: nearby same-type mobs join the fight when a buffed mob is attacked by a player, with per-mob cooldowns
- Smart goal injection that preserves vanilla AI where possible
💎 Loot & XP Scaling
- XP drops scale with the mob's effective buff multiplier (attributes, dimension, presets, day, adaptive)
- Extra loot rolls granted based on scaling strength, with configurable caps
- Doubled during a Blood Moon when enabled
- Elite bonus rewards stack on top for a proper endgame payoff
🎨 Visual Feedback
- Color-coded particle effects for different buff types and traits
- Enchantment table particles for Elite mobs and magical variants
- Per-trait and per-elite particle configuration (including RANDOM and NONE)
- Toggleable visual effects for performance optimization
🎯 Advanced Filtering System
- Mob Filtering: Whitelist/blacklist specific mobs
- Mod ID Filtering: Target mobs from specific mods
