Harry Potter and the Deathly Hallows - Part 1

The leveling trophies are all very easy to achieve and understand. Leveling is done rather quickly in this game. Points to level up can be earned by defeating enemies, collecting prophets, quibblers and potterwatch passwords, or finding deathly hallows symbols. I was able to reach level 20 well before the game ended, and made it to about level 25 or 26 if I recall correctly. This should come naturally during gameplay, especially on Hard mode.
