⚔️ NPC Slayer Enchantments - SimpleEnchantments Addon

NPC Slayer Enchantments is a fully config-driven plugin for Hytale servers that adds custom weapon enchantments granting bonus damage against specific NPC types. No coding required — every enchantment, target, damage value, and crafting recipe is defined in a single JSON file that you can edit and reload without recompiling.

🎯 Goal

The goal of this plugin is to give server owners a flexible system to create hunter-style enchantments — rewarding players who specialize in fighting specific enemy types. Want a sword that deals extra damage to stone golems? A blade that shreds through goblins? Configure it in the JSON, restart the server, and it's live.

Every enchantment integrates natively with Simple Enchantments — scrolls appear in the crafting system, tooltips show the bonus, and activation effects fire just like any built-in enchantment.

✨ Features

🔧 Fully config-driven — add unlimited enchantments via JSON, no Java required
🎯 Per-enchantment NPC targeting — each enchantment has its own list of target NPC IDs
📈 Custom per-level damage values — define exact % bonus for each level independently
📜 Full scroll integration — custom crafting recipes per level with quality tiers
🔁 Hot-swappable config — edit the JSON and restart to apply changes
⚙️ Simple Enchantments compatible — scrolls, tooltips, and activation events all work natively

📦 Requirements

Simple Enchantments v0.9.0+

🛠️ Configuration

On first server start, the plugin automatically creates the config file at:

saves/<world>/mods/SlayerEnchantment/config/slayer_enchantments.json

Edit this file to add, remove, or modify enchantments. Restart the server to apply changes.

📝 Example Configuration

The following example defines two enchantments — Slayer (bonus damage vs stone golems) and Berserker (bonus damage vs humanoid enemies):

Config Fields Reference

Field	Description
`id`	Unique enchantment ID, format `namespace:name`

🔍 Finding NPC IDs

NPC type IDs appear in your server logs whenever an NPC dies:

NPC death detected: npcTypeId=goblin_miner, role=Goblin_Miner

Use the value from npcTypeId in your targetNpcIds list. Matching is case-insensitive.
