More RPG Library adds a variety of status effects organized into harmful and beneficial categories. Each effect has unique mechanics and interactions.

​
Harmful Effects

​
Fire & Heat Effects

Ignited

Burns the target, dealing damage over time and reducing healing. The target cannot move or attack.Color: 0xFF6600 (Orange)Category: HarmfulDamage: 1.0 + (amplifier × 0.1) every 10 ticksImpairment: Movement and attack disabled

Molten Armor

Reduces armor and armor toughness, dealing damage if the target wears armor. Does not work in water.Color: 0xdd4e00 (Dark Orange)Category: HarmfulArmor Reduction: -10% (multiplicative)Armor Toughness: -1.0 (flat)

​
Ignited Effect Implementation

@Override
public boolean applyUpdateEffect(LivingEntity entity, int amplifier) {
    float baseDamage = 1.0F;
    float scaledDamage = baseDamage + (amplifier * 0.1F);
    entity.timeUntilRegen = 0;
    entity.damage(entity.getDamageSources().onFire(), scaledDamage);
    return true;
}
Molten Armor automatically removes itself when the entity enters water or removes all armor pieces.

​
Frost Effects

Frozen Solid

The entity cannot move, attack, or jump. Takes additional damage when hit.Color: 0x3beeff (Ice Blue)Category: HarmfulDamage Taken: +15% (multiplicative)Frost Vulnerability: Flat 10%, Multiplicative 20%Removal: Hit by direct damage or exposed to fire/lava

Frosted

Reduces movement speed and adds freezing ticks. Converts to Frozen Solid at amplifier 5.Color: 0x3beeff (Ice Blue)Category: HarmfulMovement Speed: -5% per stack (multiplicative)Conversion: Amplifier 5 → Frozen Solid (100 ticks, amplifier 0)

​
Frozen Solid Mechanics

public void onApplied(LivingEntity livingEntity, int amplifier) {
    super.onApplied(livingEntity, amplifier);
    EntityType<?> type = livingEntity.getType();
    if(type.isIn(EntityTypeTags.FREEZE_IMMUNE_ENTITY_TYPES)) {
        livingEntity.removeStatusEffect(MRPGCEffects.FROZEN_SOLID.entry);
    }
}
Frozen Solid is removed when hit (configured with RemoveOnHit.Trigger.DIRECT_HIT) and makes entities completely incapacitated.

​
Physical Damage Effects

Bleeding

Damages the target over time with scaling based on missing health.Color: 0xdd4e00 (Blood Red)Category: HarmfulBase Damage: 1.0 + amplifier per tickHealth Scaling:
  • Below 75% HP: +1% max health
  • Below 50% HP: +2.5% max health
  • Below 25% HP: +5% max health

Stagger

Reduces armor, attack damage, movement speed and incapacitates the target.Color: 0xb3b3b3 (Gray)Category: HarmfulAttack Damage: -80% (multiplicative)Armor: -80% (multiplicative)Movement Speed: -80% (multiplicative)Impairment: Incapacitated

​
Bleeding Damage Calculation

float bleedingTickDamage = 1.0F + amplifier;
float currentHealthPercentage = entity.getHealth() / entity.getMaxHealth();
if(currentHealthPercentage <= 0.75F){
    bleedingTickDamage = bleedingTickDamage + (entity.getMaxHealth() * 0.01F);
}
if(currentHealthPercentage <= 0.5F){
    bleedingTickDamage = bleedingTickDamage + (entity.getMaxHealth() * 0.025F);
}
if(currentHealthPercentage <= 0.25F){
    bleedingTickDamage = bleedingTickDamage + (entity.getMaxHealth() * 0.05F);
}
Bleeding becomes extremely deadly below 25% health - the damage ramps up significantly to create execute-style gameplay.

​
Debuff Effects

Carve

Reduces armor and increases damage taken.Color: 0xdd4e00 (Dark Orange)Category: HarmfulArmor: -10% (multiplicative base)Damage Taken: +5% (multiplicative base)

Grievous Wounds

Reduces healing taken and increases incoming damage.Color: 0x01d9cf (Teal)Category: HarmfulDamage Taken: +5% (multiplicative)Healing Taken: -10% (multiplicative)

Fear

Reduces attack damage and incapacitates the target.Color: 0x01d9cf (Teal)Category: HarmfulAttack Damage: -25% (multiplicative)Impairment: Incapacitated

Soaked

Extinguishes fire and makes the target vulnerable to frost, lightning, and water spells.Color: 0x01d9cf (Teal)Category: HarmfulLightning Vulnerability: Flat 15%, Multiplicative 10%Frost Vulnerability: Flat 15%, Multiplicative 30%

​
Special Effects

Fatal Poison

Inflicts damage over time and can kill both undead and non-undead mobs.Color: 0x5d2f8c (Purple)Category: HarmfulSpecial: Unlike vanilla poison, this effect can kill entities and affects undead mobs.

​
Beneficial Effects

Collected Soul

Increases soul spell power per stack.Color: 0x01d9cf (Teal)Category: BeneficialSoul Power: +0.10 per stack (additive)Identifier: more_rpg_classes:collected_soul

​
Action Impairing Configuration

Several effects use the ActionImpairing system to control entity behavior: 
ActionImpairing.configure(FROZEN_SOLID.effect, MRPGCActionImpairing.FROZEN);
ActionImpairing.configure(IGNITED.effect, MRPGCActionImpairing.IGNITED);
ActionImpairing.configure(FEAR.effect, EntityActionsAllowed.INCAPACITATE);
ActionImpairing.configure(STAGGER.effect, EntityActionsAllowed.INCAPACITATE);

​
Applying Effects in Spells

Use these effects in your spell impact configurations: 
{
  "impacts": [
    {
      "action": "STATUS_EFFECT",
      "effect": {
        "effect_id": "more_rpg_classes:frozen_solid",
        "duration": 100,
        "amplifier": 0
      }
    }
  ]
}

​
Effect Synergies

Frosted → Frozen Solid: Stack Frosted to amplifier 5 to automatically convert to Frozen Solid for a hard CC chain.Bleeding + Low Health: Bleeding damage scales dramatically at low health - combine with execute abilities.Soaked + Frost Spells: Soaked increases frost vulnerability by 15% flat + 30% multiplicative for devastating combos.

​
Particles and Visual Effects

Many effects have custom particle effects defined in the client package:
  • BleedingParticles - Blood drops for bleeding effect
  • FrostedParticles - Ice crystals for frosted effect
  • FrozenSolidRenderer - Ice block overlay for frozen solid
  • IgnitedParticles - Flame particles for ignited effect
  • MoltenArmorParticles - Lava drips for molten armor
  • PoisonParticles - Purple clouds for fatal poison
  • SoakedParticles - Water droplets for soaked effect
See Visual Effects for more details on particle systems.
