Sonic World Adventure Rush!

"One last thing is the types of encounters you will experience. These will determine what enemy you'll engage with what you just learned.

"The first type is RANDOM ENCOUNTER. Every new location has it's own table of the types of enemies indigenous to that area. When told to do so, or given the option, a roll of two die will reveal which enemy you will engage at that moment. You can flee from these battles if you want to, but then you won't gain experience.

"The second type is STORY ENCOUNTER battles. These are reserved for special enemies and BOSS CHARACTERS.

"Bosses are stronger, and have more lethal attacks. When one of these is encountered, you must evaluate your injuries after every round of combat, and if you roll a 12, the boss has killed you automatically! So be careful!

"You can sacrifice a combat round to heal your injuries, but a 12 is still dangerous!"
