Details
Health Regeneration will do it's namesake, and enables you to slowly regenerate health. It's very useful in achievements and the Tournament, but when it comes to the levels, is nearly useless seeing as Stay Untouched gives you extra score and unlocks medals. However, when you do get damaged, it becomes very useful, especially when in a boss fight.
