Crystal Leveling - Dynamic Mob Difficulty System

This mod fundamentally changes the combat approach in Minecraft by implementing a progressive difficulty level system for all creatures in the game.

Every creature that appears in the world automatically receives a random difficulty level from 1 to 100. Based on this value, the mod enhances the mob's characteristics, making it a more dangerous opponent. Visually, the difficulty level is displayed using a colored crystal icon next to the creature's name, allowing for instant assessment of its threat level.

Depending on the difficulty level, mobs receive enhancements to:

  • Maximum health
  • Attack damage
  • Armor rating
  • Armor toughness

The crystal color coding ranges from green for weak creatures to multicolored for the most dangerous top-level opponents.

Example of difficulty progression (from lowest to highest):

For Developers

The mod adds a syncable difficulty_level attribute (0–100) to all entities. Other modifications can use this value to create custom logic — for example, configuring loot drops, creating loot tiers, or applying special effects.

@Mod.EventBusSubscriber
public class CustomDropOnDeathWithTiers {
    @SubscribeEvent
    public static void onLivingDeath(net.minecraftforge.event.entity.living.LivingDeathEvent event) {
        LivingEntity entity = event.getEntityLiving();
        if (entity == null)
            return;

        // Reading difficulty level (default to 0 if missing)
        double difficulty = 0;
        if (entity.getAttributes().hasAttribute(CrystalLevelingModAttributes.DIFFICULTY_LEVEL.get())) {
            difficulty = entity.getAttribute(CrystalLevelingModAttributes.DIFFICULTY_LEVEL.get()).getBaseValue();
        }

        // Determining tier and giving corresponding loot
        if (difficulty >= 81) {
            // Top tier (multicolored): very rare reward
            entity.spawnAtLocation(new ItemStack(Items.NETHER_STAR), 0.0F);
        } else if (difficulty >= 65) {
            // Dark blue tier: rare reward
            entity.spawnAtLocation(new ItemStack(Items.DIAMOND), 0.0F);
        } else if (difficulty >= 49) {
            // Light purple tier: uncommon reward
            entity.spawnAtLocation(new ItemStack(Items.EMERALD), 0.0F);
        } else if (difficulty >= 33) {
            // Red tier: moderate reward
            entity.spawnAtLocation(new ItemStack(Items.IRON_INGOT), 0.0F);
        } else if (difficulty >= 17) {
            // Yellow tier: common reward
            entity.spawnAtLocation(new ItemStack(Items.GOLD_INGOT), 0.0F);
        } else {
            // Green tier: basic reward
            entity.spawnAtLocation(new ItemStack(Items.APPLE), 0.0F);
        }
    }
