AlaHorde — Hostile mobs that level up

Hostile Minecraft mobs grow stronger as you kill them. AlaHorde tracks every kill of every hostile species (zombies, skeletons, creepers, witches, endermen, blazes, ghasts, even the Wither and Ender Dragon) across the entire world. Hit a threshold for a species and every new spawn of that species comes back stronger — more health, more damage, faster, with bigger XP rewards.

The world remembers. The horde adapts.

What it does

• 25 kills per level by default — fully configurable
• Level cap at 20 — kills are still counted past it
• RPG-style [Lv.N] label above each spawned mob with color tier (gray Lv.1 → white → yellow → gold → red)
• No X-Ray — labels are occluded by solid blocks; you only see the level when the mob is in line of sight
• Bosses included — Wither, Ender Dragon, Warden scale by the same formula. Boss AI phases stay intact (we only touch attribute base values)
• Level-up announcements — chat broadcast (configurable radius) plus flame/smoke particles at the kill site
• Per-world progress — survives restarts, persisted in world SavedData

Commands

Configuration

Every option is editable from the in-game Mods → AlaHorde → Settings screen, or by hand in <world>/serverconfig/alahorde-server.toml.

Highlights:

• general.enabled — master switch. When off, the mod is fully inert (no scaling, no labels, no kill counting). Lets you A/B test against vanilla without removing the jar.
• general.killsPerLevel — kills required per level-up (default 25)
• general.maxLevel — level cap (default 20)
• general.excludedMobs — entity ids opted out of the system (e.g. ["minecraft:bat"])
• scaling.* — HP / damage / speed / XP per-level multipliers
• visuals.* — toggle the level label, level-up chat message, and notify radius

Compatibility

• Multiplayer: progress is stored per-world and shared across all players on the server. Vanilla clients can join — no client-side mod required for core gameplay (the level label uses vanilla custom-name rendering).
• Other mods: mob categories from other mods are respected. Use excludedMobs to opt out specific species.
• Modpacks: zero hard dependencies. Drop in and go.

AlaHorde

Hostile mobs grow stronger as you kill them — a global per-species kill counter raises HP, damage, speed and XP for every new spawn.

• Minecraft: 1.21.10 (26.1.2)
• Loader: NeoForge 26.1.2.28-beta
• Side: both client and server (vanilla clients can join a server with this mod)
• License: MIT
• Languages: English, Русский, Українська, Deutsch, Español, Français, Português (BR), 日本語, 简体中文, Polski

How it works

Every hostile mob (MobCategory.MONSTER — zombie, skeleton, creeper, witch, enderman, blaze, ghast, wither, ender dragon, warden, …) has its own world-wide kill counter. Every 25 player kills of a species bumps that species to the next level — every NEW spawn of that species after that point comes in stronger.

Cap at level 20 by default. All thresholds and multipliers are configurable in serverconfig/alahorde-server.toml or via the in-game Mods → AlaHorde → Settings UI.

Each spawned mob gets a styled [Lv.N] label above its head, color-tiered by level (gray Lv.1 → white 2-5 → yellow 6-10 → gold 11-15 → red 16-20). The label is occluded by solid blocks — no X-Ray cheating; the level only shows when the mob is in line of sight.

When a species levels up, all players within the configured radius get a chat broadcast and flame/smoke particles burst at the kill site.

Bosses (Wither, Ender Dragon, Warden) are included by default — only attribute base values are touched, so boss AI phases stay intact.
