Thief (Ash and Magic 2)

Ashley is faced with an impossible choice: help a demon lord steal from the College of War magic so that he can in turn help her cheat at dueling, or flunk out of second year at Wizard University!

What will she do?

The only thing she can: summon a fairy and plan a heist! It's only the most heavily guarded vault in the entire University, sitting underneath the home of the most powerful magical warriors that the world has ever seen. There are probably traps and sensors and magical defenses of all kinds, not to mention the man she's stealing from is Professor Smith, a powerful War mage who seems to hate her. What could go wrong?
