Q3.88. Gold Rush
Phase 1. The Bank Robbery
After doing the Q3.60. Posh Reception, you can meet a child (M20.11) on the street, who will tell you that there's a bank robbery going on and Velerad needs your help. Follow the kid and talk to Velerad near the bank (M14.30).
Phase 2. Siegfried
If you choose to say that "he might have stayed out of trouble", you'll get a key to the warehouse (M14.39) and be able to get into the bank quietly. Watch out for a pack of Fleders there. Get to the Town Hall and then to the bank. You'll end up in phase 13.
Phase 3. Siegfried
If you don't use the passage through the warehouse, it'll turn out that Siegfried went inside the bank.
Phase 4. Helping Siegfried
You have to join him now.
Phase 5. The Operation
Enter the bank through the main entrance. Inside there is Siegfried who'll tell you to use another way to avoid the Scoia'tael arrows.
Phase 6. Entering through Town Hall
Leave the bank and follow Siegfried - you'll get through the town hall. Inside you'll meet some elves and you'll be able to decide whether to negotiate with them or not.
