LevelMobs

This plugin, called "LevelMobs," primarily modifies hostile entities (mobs) upon spawning by assigning them a level.

This level has the following consequences:

• Attribute Scaling: Increases the monster's maximum health, attack damage, and movement speed in proportion to its level, with a configurable maximum health limit (100.0).
• Equipment: Randomly grants armor pieces (leather, gold, iron, or diamond) and weapons (swords or bows) with enchantments (such as Protection, Edge, or Power) whose strength depends on the monster's level.
• Health Bar: Adds a visible name to the entity, showing its level and current health in the form of a health bar (e.g., Lv. 10 ZOMBIE | 50.0/50.0 ❤).
• Enhanced Rewards: Upon death, leveled-up monsters drop bonus experience and have a chance to drop extra items (such as iron, gold, diamonds, or experience bottles) based on their level.

The add-on introduces levels in two ways:

• Naturally: There is a configurable chance (20% by default) that a naturally spawning monster will receive a random level (between 1 and 30).
• By Command: Administrators can use commands to spawn monsters with a specific level.

In addition, the add-on includes a "Horde" system:

A command (/levelmobs horde [level]) allows administrators to summon a horde of 6 to 10 level-matched monsters near them.

There is a small chance (0.5% by default) that a level-matched horde will spawn naturally near a player.

Finally, the plugin provides management commands (/levelmobs and /levelmobs_toggle) to spawn these mobs manually, toggle the natural leveling system on or off, and command autocompletion for ease of use.
