Regular Expedition
All ships participating in the expedition must have at least 50 morale ('sparkling') for a chance at Great Success. The chance for Great Success increases approximately 19% per sparkling ship.

Drum Expedition (21, 24, 37, 38)
Ships with 50+ morale still increase the chance of Great Success, but at a lower rate of approximately 16% per sparkling ship.
