even if u using total 18 drum (equipping all of your ship with 3 drum), it still only yield around 50-60% great success based on my experience.. so u still sparkle some of them.. usually i sparkle 4 ship, with minimum drum requirement, alrd give me 95% chance great success (or even 100%, i think my fleet never fail to get great success)
