Monster Rancher 4 Cheats

Easy Wins
Here's a good tip for beginning monster ranchers: when training a monster, raise every stat to at least level ten except for power and accuracy, which should be raised to at least level 20. During a battle, such a monster will usually be able to attack past an opponent's defence and can deliver KOs easily.
