Here's the code. I'll comment it if you guys are interested (tell me in the comments):

public class ItemPOW : MonoBehaviour
    {
        protected Item item;
        protected ItemModulePOW module;
        public float forceMultiplier;
        public Collider POW;
        public float POWTimer = 0f;
        public float POWCooldown = 0.5f;
        public int i = 0;

        protected void Awake()
        {
            item = this.GetComponent<Item>();
            POW = item.GetComponentsInChildren<Collider>()[2];


            item.OnCollisionEvent += OnPOWCollisionEvent;
            module = item.data.GetModule<ItemModulePOW>();
            forceMultiplier = module.forceMultiplier;
   

        }

        void OnPOWCollisionEvent(ref CollisionStruct collisionInstance)
        {
            if(collisionInstance.sourceCollider == POW || collisionInstance.targetCollider == POW)
            {
                if (POWTimer > POWCooldown)
                {
                    POWTimer = 0f;
                    foreach (Creature npc in Creature.list)
                    {
                        if (npc != Creature.player)
                        {
                            if (npc.state == Creature.State.Alive || (npc.state == Creature.State.KnockedOut && npc.ragdoll.isGrounded) || (npc.state == Creature.State.Dead && npc.ragdoll.state == BS.Ragdoll.State.Dead))
                            {
                                if (npc.state == Creature.State.Alive)
                                {
                                    npc.ragdoll.SetState(BS.Ragdoll.State.Fallen);
                                }
                                if(npc.state == Creature.State.Dead)
                                {
                                    npc.ragdoll.SetState(BS.Ragdoll.State.Fallen);
                                }
                                foreach (RagdollPart ragdollPart in npc.ragdoll.parts)
                                {
                                    ragdollPart.rb.AddForce(Vector3.up * forceMultiplier, ForceMode.Impulse);

                                }

                            }
                        }
                    }
                }
            }           
        }

        void FixedUpdate()
        {
            foreach (Creature npc in Creature.list)
            {
                if(npc.ragdoll.isGrounded && npc.state == Creature.State.Dead)
                {
                    npc.ragdoll.state = BS.Ragdoll.State.Dead;
                    npc.ragdoll.isGrounded = false;
                }
            }
            POWTimer += Time.deltaTime;
            
        }
}
