Laravel 5.4 Model Properties and Methods Inheritance - php

Question

The main model is BaseMonster, with all the basic informations of a monster (stats, monster type, etc) that will be inherited by child classes.
At the moment, I have two child classes named WildMonster and PlayerMonster, related to BaseMonster with a one to many relationship (from BaseMonster side).
My main goal is to be able to inherit attributes like stats, names and images and all the related methods from BaseMonster to other child monster classes.
This way i can avoid db redundancy for common attributes and at the same time adjust various aspect of certain child monsters just editing theirs parent BaseMonster record.
Example: "Kraken" monster has too high attack stat value. With a simple change to its BaseMonster record, all WildMonster and PlayerMonster instances related to "Kraken" are affected.
I want to avoid code redundancy too, for example making one rating() method in BaseMonster that will use all the actual stats (along with stat bonuses and levels) of the monster instance and that can be used by any of the monster child classes.
I tried accessing parent properties with Laravel accessors, and setting them to the Eloquent base_monster relationship stat, but this way i can't work with children attributes, like level or health_bonus to adjust values accordingly. (or at least i didn't find the right way).
I also tried setting accessors from child side with half a success, but anyway this mean i have to write the same accessors in all child classes and to make a huge mess if i want to change something.
How can I achieve something like this in laravel 5.4?
Extract of attributes
BaseMonster is the parent of the other monster classes and contains all the common attributes and methods needed in most of the occasions. BaseMonsters are created by Game Admin to manage things like stats and images and to generate new WildMonster to populate various Dungeons.
BaseMonster (extends Model)
name
image
health
attack
defense
monster_type_id (relationship with the MonsterType model)
WildMonster is the monster encountered in dungeons or in other ways. Can "transform" to PlayerMonster if recruited.
WildMonster (extends BaseMonster)
name (to customize name for special encounters)
level (to adjust stats accordingly)
health_bonus (there is a chance a monster has various stats bonuses)
attack_bonus
defense_bonus
base_monster_id (relationship with the BaseMonster model)
PlayerMonster is the monster recruited by the player after a battle.
PlayerMonster (extends BaseMonster)
name (eventually customized by the player)
level
health_bonus
attack_bonus
defense_bonus
base_monster_id (relationship with the BaseMonster model)

What you are looking for is called Polymorphic Relations in Laravel. This way you can define a base model BaseMonster as requested. Following the example on the site:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class BaseMonster extends Model
{
public function monster_wild_or_player()
{
return $this->morphTo();
}
public function monster_type()
{
return $this->hasOne('App\MonsterType');
}
}
class PlayerMonster extends Model
{
public function base_info()
{
return $this->morphMany('App\BaseMonster', 'monster_wild_or_player');
}
}
class WildMonster extends Model
{
public function base_info()
{
return $this->morphMany('App\BaseMonster', 'monster_wild_or_player');
}
}
