Stealing The Philosopher's Stone

You and your wizard friends are out for a fun night at the pub when all of the sudden you're approached by a dapper looking gent. He has a job that needs doing and he thinks your group might be the ones to get it done. All you'll have to do is finish up your drinks, head onto the street, and try to break into the goblin Bank. You have 1 hour before security makes their way back to check on things so you'll need to work fast. Good luck on this magical adventure.
