Mob Level

Every mob now has a level. Survival just got a difficulty curve.

MobLevel attaches a level to every creature in the world. That level silently rewrites the mob's health, damage, drops, and experience. A level-3 zombie is a pushover. A level-150 zombie is a boss fight you didn't ask for — faster than you, immune to the sun, and it cheats death once.

The catch: power has to be earned and found, not farmed in an afternoon.

How leveling works

Level 20 is the vanilla baseline — a level-20 cow is exactly the cow you already know. From there:

• Below 20 mobs are weaker than vanilla and their loot gets scarcer the lower they go.
• Above 20 mobs scale up in health, damage, loot, and XP.

Low-level animals dropping less is intentional — a level-1 cow gives you a single steak, and only one time in four. The good loot lives at the top.

High levels are rare on purpose

Hostiles and passives roll on two separate curves. Monsters despawn and get replaced constantly, so a generous tail there is self-limiting. Farm animals never despawn, so every high roll is permanent — they are held to a much harsher curve.

Level 150: apex mobs

The top of the curve isn't just a bigger health bar. Purple particles mark them from a distance — approach at your own risk.

See it in action

Creepers are a special problem

Creeper blast radius scales with level: 3 blocks at level 1, up to 12 at level 150. A high-level creeper doesn't just hurt more, it removes substantially more of whatever you built.

Breeding: the long game

Animals pass their levels to their children — the offspring inherits the average of its parents, rounded down. Two level-40 cows make a level-40 calf. A level-150 bull and a level-50 cow make a level-100 calf, not a level-150 one.

So how do you ever climb? Mutations.

There is no shortcut. A level-100 herd is a genuine long-term project, not a five-minute exploit.

The spyglass is a level scanner

Names only show up when you're close and looking at a mob. Scope a spyglass and you can read a mob's level from up to 100 blocks away — through the scope only, and never through walls. Scouting before you commit is a real option.

Boss mobs stay fair

The Ender Dragon and the Wither are clamped to a sane level range (20-80 by default), so they scale up without turning into unkillable health sponges.

Villagers and traders level up too

Villagers and wandering traders have levels, and their trades follow the same curve. Level 20 is vanilla.

At a glance

• Levels drive health, damage, loot, and XP together, on separate curves
• Color-coded names reveal a mob's level when you look at one
• Particle auras mark the most dangerous mobs
• Despawn-safe by design — levels live in entity tags and the label is drawn client-side, so vanilla naming, persistence and despawn rules are untouched and hostile mobs never pile up
• Fully configurable — spawn rarity, scaling curves, breeding odds, and boss limits are all tunable
