Fatal Labyrinth/Ranks

As you gain levels, you will earn various titles. Each title is earned when you reach a certain amount of HP. Each time you gain a new title you lose the previous title.

Initially (at Beginner level) you gain 1 HP every time you level up. Each higher ranking you reach increases HP growth (so you gain 2 HP per level as a Valet, 3 HP per level as a Ranger, and so forth).
