    27.             if(e.getCause().equals(EntityDamageEvent.DamageCause.ENTITY_ATTACK)) { //Get the attack cause.
    28.                 for(Entity ent : p.getNearbyEntities(1.5D, 1.5D, 1.5D)) //Check nearby entities for possible damagecause

    32.                 {
    33.                     if((ent instanceof Zombie)) // If it equals to a zombie (almost only close range mob which counts as ENTITY_ATTACK)
    34.                     {
    35.                         p.addPotionEffect(new PotionEffect(PotionEffectType.BLINDNESS, 30, 1)); //Add the PotionEffect
    36.                         p.addPotionEffect(new PotionEffect(PotionEffectType.SLOW, 10, 1)); //Add the PotionEffect
    37.                         e.setDamage(3.5);
    38.                     }
    39.
