FelMobs

FelMobs

Turn ordinary mob encounters into configurable Rare and Elite challenges.

FelMobs gives eligible mobs a configurable chance to become stronger Rare or Elite variants. Enhanced mobs can receive improved attributes, distinctive nameplates, combat modifiers, extra experience, personal bonus drops, custom loot, and optional economy rewards.

Every included YAML file contains explanatory comments, accepted values, examples, units, and precedence information.

Default behaviour

• Eligible hostile and neutral mobs have a 5% Rare chance and 1% Elite chance.
• Every spawn source qualifies, including natural spawning, spawners, spawn eggs, breeding, commands, and plugin-created mobs.
• Rare mobs receive one modifier; Elite mobs receive two or three modifiers.
• Rare mobs have 1.5x health by default; Elite mobs have 3x health.
• Bosses, tamed mobs, and custom-named mobs are excluded by default.
• Passive mobs are supported but disabled by default.

Features

• Independent Rare and Elite tiers with configurable chances, aliases, attributes, modifier counts, and rewards
• Ten modifiers: Regenerating, Vampiric, Blazing, Venomous, Swift, Warping, Summoner, Resistant, Shielded, and Enraged
• Configurable nameplates with health, tier, mob, modifiers, location, and PlaceholderAPI values
• Personal damage-contribution tracking with individual reward thresholds
• Owner-locked bonus drops for qualifying participants
• Vanilla-drop and experience multipliers
• Weighted custom loot tables and console reward commands
• Optional Vault currency rewards
• Per-mob eligibility, chance, and modifier overrides
• World, dimension, biome, region, and spawn-reason rules
• Persistent enhanced mobs that retain their tier and modifiers
• Optional spawn and death announcements
• Per-player particle, sound, message, and announcement preferences
• Heavily commented configuration files
