The battle system itself is very similar to previous Dragon Quest Monsters games. You have up to three monsters in your party, you can issue them direct orders or set them to one of 4 AI settings. Your main character does not directly participate in battles except for using items when told to do so. Dragon Quest Monsters: Joker does not have random battles. The only way to encounter enemies is to run into one on the overworld. The monsters can be seen, avoided, and attacked from behind in order to get a free attack round.
