Sky Captain and Spy Glass do not seem to help.You are very lucky, Tom. How did you get sooo many items?! I am clicking every 30 minutes. No drops or very rare. Less then 5 days to complete. And I am 0-1-3-4-3 or something till now. No way to finish successfully. Sky Captain and Spy Glass active all the time....
I now get more items than with bonus.
