HP: The Arcane Thief

A skilled thief gets a system in an Alternate Wizarding World. The system seems useless in the beginning since he hasn’t unlocked any features. But… [The very first feature of the System has been unlocked.] [Congratulations. You’ve unlocked the class feature. Due to your existing skills and experience, you have gained the Special Class "Arcane Thief" as your starting class. There’s nothing an Arcane Thief can’t steal. The more you steal, the more your Class will progress.] [The fields of expertise include: — Stealth Magic— Wards— Traps— Enchantment— Pickpocketing— Knife/Short-Sword Wielding] Wait…this is just the first feature?
