Uh oh, looks like our Hero has gotten himself surrounded!
As enemies attack and land successful hits on you, your HP will be reduced.
When your HP hits 0, you die. When your character dies in One-Person mode, you will be revived at the Medical Center. When your character dies in multiplayer mode, he or she will remain on the ground until another party member revives them or they choose to go to the Medical Center of their own accord.
When you are revived at the Medical Center, you recover full HP, TP and traps. Death can cause you to fail quests and sometimes miss out on great experience from falling in the middle of a boss fight. So, try to avoid death as much as you can!
